| Abstract: | Working principle of high temperature gas-heater is introduced in this paper. Two dimension heat transfer equations are developed. Conjugate heat transfer between the external flow field and structure of nose tip is simulated using CFD software FLUENT. The k-εmodel is used based on sperated-solver. The gas flow and heating characteristics are obtained with the variety velocity and temperature of incoming flow. The results will be helpful for the optimization of the converted heater design and converted heating experiment. |
