中文摘要: 利用汽液两相流基本理论,在质量守恒和动量守恒定律基础上得出了计算电厂直接空冷凝汽器散热器倾斜下降翅片管内压力降的计算模型.利用该模型对两个实验工况进行了计算,并将计算结果与实验结果进行了比较.该方法为计算低压冷凝换热管中的压降提供了一种新的手段.
Abstract:Using vapor-liquid two-phase flow theory and based on the mass and momentum conservation, the author educed a computing model for computing the vapor-liquid two-phase pressure decrement in power plant direct air-cooled condenser tube. This model is a new one for computing the vapor-liquid two-phase pressure decrement in lower pressure condensing heat trans for tube. Using the model, the author computes two states and compares the results from experiment. Results show that the computed model the author puts forward is good for computing the vapor-liquid two-phase pressure decrement.
