Abstract: A code was developed by using the basic principles of aerodynamics,heat transfer,thermodynamics and numerical heat transfer taking into account the compound relationship among pressure difference,mass flow,temperature difference and heat flux,including the influence of heat convection between cooling air and inner surface of film cooling holes.Using this code we can calculate the two dimensional temperature field of burner inner liner with annular slots and multi film cooling hole by giving the air/gas parameters at the inlet and outlet of the combustion chamber.
