摘要
通过引入无因次温度分布式 ,求解缩放管内任一截面的传热斯坦顿数 ,并以此为基础导出了缩放管整体传热准数预测公式。根据相似律又可得传质斯坦顿数的预测公式 ,并把所得结果与文献 [2 ]提供的实验数据进行了对比 ,相对误差小于 7%。
The Stanton Number for each cross section of converging-diverging tube is investigated by adapting the dimensionless temperature distribution normal to the wall of the tube, and the prediction formulae for heat transfer are obtained. The corresponding mass transfer formulae were also obtained by analogy rule. The theory results correspond with experimental results, and the maximum deviation of the formulae results with experiment data is less than 7%.
