Corrugated plate heat exchanger (CPHE) is the most utilized compact heat exchanger (HE) due to its high thermal performance. The present study is conducted for modified CPHEs with chevron angles β = 60°/60° and 30°/30°, and for conventional CPHE with β = 30°/30°. The characteristics of flow resistance along with other important physical parameters inside the modified and the conventional CPHEs are presented in this study. Acomputational Fluid Dynamics (CFD) approach is employed to conduct the present study, where realizable k − ε turbulence model is used. The numerical simulations results are validated against available experimental data in the literature. The overall thermal performance is examined by calculating the ratio of the heat transfer rate to the ratio of increase in the pumping power (JF factor). The core pressure drop, fanning friction factor (f), turbulence kinetic energy (TKE), and port maldistribution have been investigated. The findings are compared against those of conventional CPHE with β = 60°/60°. The modified and the conventional CPHEs are alike in geometrical and physical tests conditions. The simulations are performed for single-phase (water-water), counter-current flow, and for a range of Reynolds number (Re = 500 to 2000). The results show that f data of the modified CPHEs are ~4.5–7 fold higher than those of the conventional CPHEs. The data of port maldistribution of conventional CPHEs are found up to ~8 times greater than those of the modified ones. The TKE of the modified CPHEs is found ~2–3 times higher than those of the conventional ones. In addition, due to the high pumping power requirements of the modified CPHEs, their JF data have been found 1.1–1.5 fold lower than those of the conventional CPHEs. The f correlations of the modified and the conventional CPHEs have been established.

波纹板式换热器（CPHE）由于其较高的热性能而成为最常用的紧凑型换热器（HE）。本研究针对人字形角度为β = 60°/ 60°和30°/ 30°的改进型CPHE，以及针对β = 30°/ 30°的常规CPHE 。本研究介绍了改进型和常规CPHE内部的流阻特性以及其他重要物理参数。采用计算流体动力学（CFD）方法进行本研究，其中可实现k  -  ε使用湍流模型。数值模拟结果已针对现有的实验数据进行了验证。通过计算传热率与泵浦功率增加率之比（JF系数）来检查整体热性能。已经研究了堆芯压力降，扇形摩擦因数（f），湍流动能（TKE）和端口分布不均。将该结果与β = 60°/ 60°的常规CPHE的结果进行比较。修改后的CPHE和常规的CPHE在几何和物理测试条件下都是相似的。针对单相（水-水），逆流和雷诺数范围（Re  = 500至2000）执行了仿真。结果表明，˚F修改后的CPHE的数据比常规CPHE的数据高约4.5-7倍。发现传统CPHE的端口分布不均的数据是修改后的CPHE的不超过8倍。修改后的CPHE的TKE比传统THE高约2-3倍。此外，由于修改后的CPHE的泵浦功率要求很高，因此发现其JF数据比常规CPHE的JF数据低1.1-1.5倍。已经建立了修改后的CPHE和常规CPHE的f相关性。
