The purpose of our research could be divided into three aspects: (1) to investigate heat transfer characteristics of filmwise condensation in the presence of NCG; (2) to explain the divergence among earlier researches on condensation in the presence of NCG, through the thermal resistance analysis...
During conduction heat transfer, when the surface temperatures do not vary with time, such cases can be analyzed without requiring to solve differential equations by utilizing the concept of thermal resistance. In electric circuits, current flows between two points as a virtue of a potential ...
5) minimum heat transfer 最小热量传导 6) maximum thermal resistance 最大热阻 补充资料:传热学:热阻 热阻: 反映阻止热量传递的能力的综合参量。在传热学的工程应用中﹐为了满足生產工艺的要求﹐有时通过减小热阻以加强传热﹔而有时则通过增大热阻以抑制热量的传递。
At mid-stage of solidification, the effective transient thermal resistance of the outer wall of the mold is larger than that of other heat transfer sections. Heat transfer section of the outer wall of mold is the RSHT. At late-stage of solidification, the heat transfer section of the ...
