| Abstract: | The supersonic duct flow with fixed back pressure to stagnation pressure ratio Pb/Po under heating is investigated analytically. A "Flow Pattern Diagram" which consists of six pattern zones is developed.By this diagram the actual flow state in supersonic duct flow system can be determined conveniently when Pb/Po and heating intensity are known. It is impossible for flow with heavy heating to become supersonic, even though the pressure ratio is much smaller than the critical pressure ratio. Based on the analogy between viscous effect and heating effect a thermal drag factor has been defined, which can predict the flow property variation due to heating and the relative importance of viscous effect and heating effect. |
