| Abstract: | This paper is based on the results of experimental observation. A gas liquid two phase mathematical model of air cooled condenser's horizontal stratified flow type is founded. At the same time, the steady equations correlating were set up. The calculation results including the parameters of void fraction, quality, heat transfer coefficient, vapor phase velocity and liquid phase velocity have are obtained. In the end, the effect of the gas liquid separator on the improvement of the condenser's condense performance is analyzed and calculated. |
