Abstract

A new fundamental equation of state for trichlorofluoromethane (R-11) is presented. The equation of state is valid for temperatures in the range from the triple point to 600 K with pressures to 30 MPa. Temperatures are given on the new International Temperature Scale of 1990 (ITS-90). Newly correlated ancillary functions representing the vapor pressure, saturated liquid density and saturated vapor density were used to insure proper behavior of the equation of state at phase equilibrium. A stepwise linear least squares regression algorithm was used in a multi-property fit to P-ϱ-T, coexistence densities, heat capacity and velocity of sound data. Data predicted using extended corresponding states methods were used to augment the available experimental data. Graphical comparisons are made to the experimental data to verify the accuracy of the formulation. The use of this equation for comparative studies using new ozonesafe alternative refrigerants is suggested. This equation of state may also be used as a reference fluid equation in extended corresponding states prediction methods for alternative refrigerants.

Poole and Aziz [52] introduced sound velocity in liquid R-12 and the Law of Corresponding States with AAD -5.3. A novel basic equation of state, which is true for temperatures ranging from the tripartite point to 600 K with pressures up to 30 MPa, was proposed for trichlorofluoromethane (R-11) by Jacobsen et al. [53]. An EOS model with AAD of 4.687% was introduced by Stewart et al. [54].
The thermophysical properties of refrigerating systems should be accurately understood for designing low-temperature refrigeration cycles of economic acceptance. The present work has tried to simplify this complicated procedure by proposing reliable and new correlative methods for determining thermodynamic and transport properties of four refrigerating substance classes, namely halocarbon, inorganic, hydrocarbon, and cryogenic fluids. New machine learning methods e.g., particle swarm optimisation adaptive neuro-fuzzy inference system (PSO-ANFIS), genetic programming (GP), and hybrid adaptive neuro-fuzzy inference system (Hybrid ANFIS) algorithms were utilised. The development of a new, simple and comprehensive correlation was for the first time introduced to estimate saturated vapour enthalpy, entropy, velocity of sound, and viscosity of refrigerants without having in-depth knowledge of complicated parameters. The accuracy and validity of the proposed models were assessed using a variety of statistical and graphical demonstrations. The findings were compared, and it was found that Hybrid ANFIS models are more accurate because Absolute Average Relative Errors (%AARD) for enthalpy, entropy, the velocity of sound, and viscosity were estimated as 0.5558, 1.3105, 0.5215, and 1.5727 in respective order. In addition, the proposed models' results were compared to the results of recently previously published models, and it confirms the reliability of our results. The innovation of this research is the design of reliable correlative methods having elevated precisions for thermodynamic and transport specifications of refrigerating substances.
Systematic analysis of additives on the performance parameters of sCO<inf>2</inf> cycles and their individual effects on the cycle characteristics
2022, Energy
Compared to existing technologies, thermodynamic cycles based on supercritical carbon dioxide (sCO₂) are leading to higher efficiencies and reduced component sizes. However, it is possible to further improve the performance of sCO₂ power cycles by using mixtures of CO₂ with suitable additives, as also discussed in the literature for different applications.
This work investigates the potential to optimize the characteristics of sCO₂ power cycles by selectively adding different substances in varying amounts to CO₂. A new methodology is proposed: By using the reference equation of state for CO₂ in combination with a multi-fluid mixture model, a theoretical screening of suitable additives was done. In the literature, studies were mainly limited to mixtures for which adjusted mixture models are available. By contrast, in this work the use of a predictive mixture model, which was recently developed at our institute, also allows to include fluids, for which no adjusted models are available. Applied to two thermodynamic cycles, changes in efficiency compared to the use of pure CO₂ have been evaluated. Several promising mixture candidates have been identified. Additionally, individual effects on the cycle characteristics as well as shifts of the critical points have been investigated and are discussed.
Enhanced thermal efficiency organic Rankine cycle for renewable power generation
2021, Applied Thermal Engineering
The Organic Rankine Cycle (ORC) technology is recognized to supply electricity from low temperature waste heat and solar energy sources. When the ORC system is heated by solar energy it uses two-fluids and two-loops, producing a relatively low thermal efficiency. To increase the ORC applicability, a solar energy assisted ORC system of single loop is proposed. The aim is to reduce the ORC heat transfer losses, minimize the equipment initial and maintenance cost and enhance the thermal efficiency. This is achieved by using bladder tanks which may improve drastically the ORC technical and economic performance. This method allows the heating to vary in the collector keeping the turbine inlet condition as a constant, impacting on the heat transfer losses and simplifying the configuration. The paper shows that an ORC of a single fluid can keep a constant turbine inlet despite the mass flow rate variations due to the suńs radiation incidence, therefore, reducing the risk of likely faults in the turbine caused by high frequency vibration. An ORC enhanced 10.54% thermal efficiency is obtained with 0.5 kg/s of R1233zd(E) and a pressure ratio = 5, powered by parabolic trough collectors to generate 10 kW during eight hours per day. The ORC competitiveness is dictated by a total generation cost of 54.3 $/MWh and the advantages of a single working-fluid single loop simplicity for overall configuration.
Advanced thermodynamic cycles for finite heat sources: Proposals for closed and open heat sources applications

As it is usual in combined cycles, the 3P + R includes steam reheating at the intermediate pressure level. The RDE cycle is also compared to simpler facilities consisting in ORC (see Fig. 4) using ethanol, R11 (properties from Jacobsen et al. [46] with range of applicability of the correlations up to 377 °C), propane and toluene. Beyond the specified temperature limits, the correlations have not been verified, and chemical stability has not been confirmed.
This paper analyses two non-conventional thermodynamic cycles designed to work with finite heat sources, which are suitable for maximum temperatures of about 400 °C. The Hybrid Rankine-Brayton (HRB) cycle fits well to closed heat sources and, in the paper, it is analysed considering its exergy efficiency and some requirements for the maximum and minimum temperature of the heat transfer fluid that feeds the cycle, obtaining promising results. The other one is a new proposal called Recuperated and Double Expanded (RDE) cycle, aimed to translate the good features of HRB from closed heat sources to open ones, where the performance of HRB is limited.
Both cycles are compared to some reference ones. Results show that the HRB cycle is a good candidate for finite closed heat sources, particularly with maximum temperature around 400 °C and with temperature changes of the heat transfer fluid from 100 °C to 150 °C. The RDE cycle exhibits good performance for finite open heat sources with maximum temperatures between 200 °C and 400 °C, and it behaves similarly to tri-lateral cycles.
Potential of Organic Rankine Cycles for Unmanned Underwater Vehicles

Most organic fluids are not appropriate for high temperature applications due to thermal stability. By surveying existing experimental results of organic fluids, the suitable fluids for high temperature applications are summarized, namely, Toluene [15,23], Cyclohexane [20,38,39], R11 [40,41], R113 [13,42], Neopentane [16,43], Acetone [43], R141b [13,43] and Isohexane [13,43]. Here, steam water is included as the reference case.
Steam Rankine cycles are typically employed as the power system for Unmanned Underwater Vehicles, but with the problem of low system efficiency. In this paper, Organic Rankine Cycles are proposed as an alternative, where the required output power is of the order of 10 kW. The working conditions and associated sizing constraints for power cycles operating at underwater environments are first detailed. The small-scale axial turbine is specifically designed for different operating conditions and incorporated into the system thermodynamic model. Using the established thermodynamic model for turbine and heat exchangers, various organic fluids are scrutinized to maximize system efficiency and to ensure the sizing constraint as encountered at underwater environment. Numerical results show the high-temperature dry fluid with trans-critical cycles can largely enhance system efficiency. The system efficiency of 25.32% and 23.01% is obtained using Cyclohexane and Toluene, respectively, while the sizing constraints are also satisfied. This corresponds to the increase of 6.57%–8.87% in terms of system efficiency compared to conventional steam Rankine cycles. Parameter studies are also performed to study the influence of pinch temperatures on system performance. The work provides the insight into the potential application of organic Rankine cycles for underwater vehicles.
Robust optimization of an Organic Rankine Cycle for heavy duty engine waste heat recovery
2017, Energy Procedia
A robust parametric optimization of Organic Rankine Cycles (ORC) is carried out by taking into account uncertainties in the cycle input parameters. A typical engine driving duty cycle is considered and sampled in order to construct a suitable probability distribution describing the variability of the exhaust gases mass-flow and temperature. Besides, the environmental and condensing temperatures, specific heat ratio of the waste gases, turbine and pump efficiencies are also considered as uncertain. The parameter combination that maximizes the mean cycle efficiency and minimizes its variance is sought as optimal. Six organic fluids have been taken into account, namely R245fa, R245ca, R134a, R11, R113 and Novec649, with the best results provided by R11 and R113.
