| Summary: | This research compare three different types of Crude Palm Oil (CPO) biodiesel blends, B5, B10, and B15 with
different ambient density on nozzle flow and spray characteristics by using CPO and simulated the physics flow pattern
of mixture formation with tangential velocity between biodiesel, diesel fuel, and air in the mixing chamber of RCM, to
determine the nozzle flow and spray characteristics for different injection pressure of biodiesel spray to ambient variant
conditions on mixture formation. In order to mimic the spray processes, an Eulerian-Lagrangian multiphase technique is
presented in this study. This work makes use of Computational Fluid Dynamics (CFD) Fluent to examine the spray
properties of biodiesel fuels, and the simulation took biodiesel injection into the constant volume chamber of the RCM
into account. The boundary condition is set up at a distinct ambient parameter. The presence of in-cylinder flow, the
impact of fuel type, injection pressure, and ambient variables on spray behaviour, such as spray penetration, had been
examined. Analysis of the spray penetration variation with time for various ambient parameters and different types of
biodiesel fuels revealed that the biodiesel fuels were predicted to develop their break-up more quickly due to the fact that
all fuels atomize more quickly in the presence of higher injection pressures. The effects of these various parameters were
examined in terms of spray characteristics and contrasted with the findings of the experiments |
