2023, Computers and FluidsDetailed study of single bubble behavior and drag correlations in Newtonian and non-Newtonian liquids for the design of bubble columns
2022, Chemical Engineering Research and DesignCitation Excerpt :Tsamopoulos et al. (2008), assuming steady flow and axial symmetry, investigated bubble terminal velocity and the drag coefficient of bubbles in viscoplastic liquids. Regarding the adaptation of the drag coefficient correlation of Newtonian fluids for non-Newtonian fluids, Chhabra (1990), based on the experimental result, found out that the standard Newtonian correlations can be used for prediction of the drag coefficient of solid, non-deformable spheres in pseudoplastic power-law liquids. In the same vein, Battistella et al. (2020) studies the bubble rise in non-Newtonian fluids and selected the Dijkhuizen et al. (2010a,b) drag correlation to describe the single bubble terminal velocity for bubbles in the range of 0.5–4 mm.

2021, Journal of Petroleum Science and EngineeringCitation Excerpt :There are contradictory reports regarding the impact of the fluid behavior index (n) on the settling rate of particles in non-Newtonian drilling fluids. Shah et al. (Shah, 1982) and others (Aswad and Rashid, 2014; Chhabra, 1990) have claimed that at low Rep and laminar flow regime, n significantly affects the settling rate. They have proposed empirical correlations to predict Cd as a function of Rep and n. However, other reports (Chhabra, 1990; Kelessidis, 2003; Peden and Luo, 1987) have demonstrated that Cd is independent of n, and the standard Cd vs. Rep curve can be used for particle settling in non-Newtonian fluids, as long as the apparent fluid viscosity is used to determine the Rep.
On the terminal velocity of single bubbles rising in non-Newtonian power-law liquids
2020, Journal of Non-Newtonian Fluid MechanicsCitation Excerpt :An extensive analysis of bubbles rising in viscoplastic fluids has been provided by Tsamopoulos et al. [23], where the bubble rise velocity and the drag coefficient are determined assuming axial symmetry and steady flow. Perhaps the most relevant work related to this manuscript is the one of Chhabra [24], where it has been found that standard Newtonian correlations can be adapted to well predict the drag coefficient of non-deformable, solid spheres in shear-thinning power-law fluids, as demonstrated by experimental results. A comprehensive quantitative description of the drag coefficient for bubbles rising in non-Newtonian fluids has not yet been reported in literature, to the knowledge of the authors.
