Abstract

Objective: To analyze the droplet distribution characteristics of an effervescent injector by using kerosene within a furnace. Approach: A computational approach has been adopted to study and analyze the droplet distribution statistics. For primary breakup, effervescent injector model has been used and for secondary atomization, the WAVE breakup model has been adopted. Euler-Lagrange frame is employed to simulate the interaction between gas phase and droplet phase. Contributions: In this work, the effect of the variation of model constant C2 of WAVE breakup model on droplet distribution has been studied. Around 30000 droplet samples are collected for each case (at different value of C2 ). Validation of the work has been done with the literature available. Findings: However it has been observed that at the minimal and maximal droplet size is predicted well at radial positions away from the axis at any C2 . The similar trend has been found for the Sauter Mean Diameter (SMD). However near the axis, the prediction is not good enough irrespective of any C2 . Also it has been found that with higher value of C2 , the computational results deviates much from the measured value.
