• The effect of jet inclination angle on the pollutant dispersion characteristics of a jet in a cross flow (JICF) is presented here using large eddy simulation (LES) methodology. Three different jet inclination angles with respect to the incoming cross flow are investigated after validating the simulation results of the normal case against the measurements found in the literature. Dispersion analysis of the pollutant in the cross flow is performed from two perspectives; qualitative and quantitative. The mixedness parameter is utilized to provide a quantitative measure of the dispersion. It is shown that the inclination angle modified the associated vortices in the flow and consequently increased the dispersion and spread levels.
