Recently, a number of promising, clean, alternative and renewable fuels such as hydrogen, alcohol, dimethyl ether
(DME), and biodiesel have become the focus of investigation. Among these various alternative fuels, biodiesel has
a number of properties that make it an excellent alternative fuel for diesel engines, particularly because of its very low
particulate matter (P.M.) emissions as compared with conventional diesel fuel. Moreover, the different properties
of biodiesel may influence on the cavitation pattern in a nozzle. Thus, analysis of flow cavitation for alternative fuel
applications is of great interest.
