摘　　要：本文利用流体力学和传热学的基本原理,建立管壳式换热器混合管束壳程的理论计算模型,推导理论计算模型中的摩擦系数、壳程阻力损失和传热膜系数的计算公式并利用实验数据确定了其中的修正系数。In this paper, shell-side theoretical model of non-baffle section-varied tube mixed tube bundle longitudinal shell-and-tube heat exchanger were posed based on basic theory of fluid mechanics and heat transfer. The formulas of the model for friction factor, shell-side resistance loss, heat transfer coefficient were derived. The coefficients in these formulas were obtained by experiment data.
