Numerical and Experimental Spray Analysis of Castor and Jatropha Biodiesel under Non-Evaporating Conditions

Fuel spray characteristics influence combustion, which in turn has a direct impact on engine performance and emissions. Recently, there been an increasing interest novel castor oil biodiesel. However, few investigations have performed that combine both numerical experimental biodiesel analyses. Hence, this paper, we aim to explore the behavior of jatropha by employing methods under non-evaporating, varying injection, ambient conditions. The study was carried out control volume vessel (CVV) at high injection pressures. fuel atomization modelled ANSYS Fluent using Lagrangian/Eulerian multiphase formulation. results revealed Kelvin–Helmholtz Rayleigh–Taylor (KHRT) model coupled with Taylor Analogy Breakup (TAB) provide better estimation penetration length (PL) cone angle (SCA) compared KH TAB models. On average, Jatropha (JB-20) (CB-20) showed 10% 22% longer PL, 8% 10.6% narrower angles, 3% 6% less area, respectively, diesel. predictions JB-20 CB-20 had around 24.7–48.3% larger Sauter mean diameter (SMD) 38.6–73.3% average (AMD).
