| 摘 要： | 对二侧流道相同的间壁式换热器的放热,应由试验建立准则方程。本文提出了一种试验数据处理的有效方法——逐次逼近法,阐述了此法的由来和依据。并以此法为指导,进行了传热的试验布置和测量,从而可以不测壁温(难以测取),用常规测量手段及仪表测取数据,经处理建立了准则方程。

| Abstract: | The criterion equation of convective heat transfer of heat exchanger separated by a wall with twosimilar sides fluid channels should be set up by experiment.In this paper,an effective way,the progres-sive approaching method is raised.Its deduction basis is described and it is used in conducting arrange-ment and measurement of the experiment.Therefore by means of conventional instrumentation andmeasurement the criterion equation is established without measuring the wall temperature. |
