The Study of Cylindrical Duct Cooling by Solid Hydrocarbon Fuel Gasification Products

This paper presents a model to describe heat transfer in a cylindrical duct, such as a combustion chamber (CC), where the wall is cooled by solid hydrocarbon fuel gasification products. The effects of phase and chemical transformations inside the regenerative cooling system ducts are examined taking into account the nonequilibrium state of the working flow in the CC duct. The main design requirements and the CC operating modes are determined, at which bearable temperature conditions of the wall can be guaranteed by cooling the wall by solid hydrocarbon fuel gasification products. It is pointed out that the required duct geometry depends on the air-to-fuel ratio as well as the mass flow rate of combustion products in the duct. Main requirements to the solid hydrocarbon fuel and its gasification products are formulated. Several hydrocarbon fuels are compared, and recommendations on the use of these fuels in high-speed ramjets are developed. The results obtained can be used to develop high-speed ramjets, and promising propulsion and technological systems, in which solid hydrocarbon is used as fuel.
