| Abstract: | According to the theory of heat radiation,the essential characteristic of outward radiation heat transfer of engine group was researched,and the necessary conditions for simulation research of this heat transfer phenomenon using nozzles,subscale component of electrically heated nozzles were given out to be simialr geometrically,and equal for heat flux q and emissivity ε on wall surface for the two.Feasibility analysis provides scientific basis for ground simulation test.Its conclusion can be used for guiding the test. |
