CFD simulation able to predict the behaviour of the combustion take place together with the air mixture properties as well as how the burnt air leave the burner. thus, it able to provide a clearer visualization for the particular burner design as if we directly fabricate the burner and test it physically, it may cost us a lot of times and money before we able to get a optimized burner parameter. Therefore, CFD able to eliminate cost and time problem which commonly faced by an engineer. In fact, in industry, CFD usually integrated with a PIDO software such as ModeFrontier to obtain the best parameters.
