The paper presents the simulation of the combustion of ethylene intended to be used in hybrid rocket propulsion.The simulation,was performed in ANSYS numerical codes,considering the following assumptions:fuel temperature 700 K and 800 K;pressure in the combustion chamber 1 to 3 bar;overall excess air from 1.5 to 5,in order to determine the case with lowest pollutant species.The simulation displayed the combustion temperature field,the flame OH concentration field,the exhaust gases composition fields,the gases velocity field,NO,CO,CO2 concentration fields and the gases pressure field.The simulation showed the influence of fuel temperature upon the combustion spatial features.
