在笔者所建立的吸入式风洞试验台上,采用萘异华技术对气体横掠单管及管槽内强制对流换热的相似准则式进行了校核试验,试验结果表明质交换的数据与换热关系式的最大偏差在±5.5％以内.文中对这种研究方法作了误差分析,对表面上微小昇华速度的影响及热边界条件的模拟进行了讨论。 In the suction wind tunnel test bench established by the author, a similar criterion for forced convection heat transfer within a single pipe and a tube slot of a gas swept through a naphthalene isoprene was used to verify the test results. The experimental results show that the data of mass exchange The maximum deviation of the heat exchange equation is within ± 5.5% .In this paper, the error analysis of this research method is carried out, the influence of the sublimation velocity on the surface and the simulation of the thermal boundary conditions are discussed.
