Numerical simulation on spray characteristics of ether fuels

In this study, the spray characteristics of ether fuels have been studied numerically using a new hybrid spray model in KIVA4 CFD code which accounts for cavitation inside he injector nozzle holes. The cavitation phenomenon was investigated numerically using Fluent CFD software. The properties of ether fuels have been predicted and reported. It is found that ether fuels cavitates higher compared to diesel fuel which means high fuel quantity should be injected to achieve same power output as diesel fueled engine. The spray simulation shows the atomization of ether fuels are far superior to diesel as they are characterized by high Reynolds number and low Ohnesorge number. (C) 2015 The Authors.
