Based on Tinker's flow model and the concepts of equivalent piping diagram suggested by HTRI (Heat Transfer Research Inc.), the authors, in this paper, proposed a "row by row" calculating method for solving flow ratesof WA and WE in streams A and E respectively. For practical uses, however, this "row by row" method is somewhat tedious. After some simplified treatment,

流路分析法是计算壳程压强降及传热的最新方法。我们的工作是在Tinker的流动模型和美国传热研究公司的流路网络模拟系统概念的基础上开展的。本文提出一个用以计算流路A和E的流量W_A及W_E的方法——“逐排计算法”。因“逐排计算法”用于具体设计计算时较为麻烦,所以经简化处理可得Δp_A≈1.10(Δp_束+Δp_缺)和Δp_E≈1.25(Δp_束+Δp_缺)。此结果对大多数情况来说,都很满意。 本文提出一个完整的数学模型,供计算压强降之用。 由于K值是雷诺数的函数,可将14个模型的实验数据关联以得到各流路阻力系数K的方程式。对K_缺来说,情况复杂,可表达为纯经验关联式: 利用上述数字模型及实验结果,可用试算法求解Δp_缺、Δp_束及各流路的流量。
