Abstract

In present study, the velocity and pressure of two-phase flow in flow field and the effect of inlet turbulence on trajectory and breakup of liquid jet in Crossflow are investigated numerically. Large Eddy Simulation method is used to discriminate Navier Stokes equations. A hybrid fluid volume model and level set are applied for two-phase modeling. Results show, with increasing the turbulence intensity, the vortices in the flow field store more energy. According to breakup mechanism changes the breakup length and breakup height are closed to injector output 33% and 11% respectively. Also, due to the very small amount of dynamic energy present in the turbulent fluctuations, the jet trajectory equation doesn’ t change in the different turbulence intensity. Liquid jet trajectory has been studied in different nozzle geometries. The results indicate that liquid jet trajectory is different for elliptic and circular geometries. Results are in good agreement with the results of other researchers.
