Dryout ofcQunter −current two − phase How is widely observed in the actual cbemical and ！ or industrial systems ． In case of the diabatic counter − current two − phase flow ， the upward gas increases with the hquld film evaporation along the 1毛eating tube and flooding strongly affects the dryout ofcounter − curront two − phase flow． In this investigation ， the dryout experiment was conducted with the countor − current two − phase flow consisted of the fヒ ee falling liquid film and upward gas 刊ow ． The obtained dryout characteristics were strongly inHuenced by the degree of inlet subcoooling ， and are class 正 五ed into three groups on the basis of the dryout 夏 nechanjsn1
