CFD Investigation on Nozzle Considering Fuel Properties of Alternative Fuel A Review
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2018, Vol 3, Issue 1
Abstract
In this work multi phase flow and erosion analysis were done via simulations and CFD application for standard diesel and two alternative bio fuels, FAME and DME, inside different nozzle models and with various boundary conditions. Nozzle model consists of narrow channel with sharp type I or rounded type Y inlet section, with or without downstream placed target, so there was a total of four different model geometries. Simulation results showed that cavitations was present in almost all cases and that clear difference between three observed fuels can be seen. Mass flow in channel type I was lower than one in channel type Y. When comparing three observed fuels, it was noticed that DME fuel usually had highest velocity, but lowest mass flow rate. Contrary to DME, FAME fuel showed highest mass flow rate despite lowest velocity. When comparing simulation results and physical properties of observed fuels, it can be concluded that density is a leading term in determining mass flow rate. Also, erosion model predicts more intensive MDPR value near narrow channel exit.
