摘要

为提高超临界CO

（SCO

）气体冷却器的传热效率与综合性能，本文对SCO

在内肋扭曲椭圆管内的流动与传热特性进行了数值研究，结合场协同理论对该管强化传热机理进行了分析。以节距（

）、肋高（

）、长半轴（

）及雷诺数（

）为设计变量，采用响应面法（RSM）建立了努塞尔数、摩擦系数与综合性能评价指标的二阶响应面模型，并采用非支配遗传算法（NSGA-II）开展多目标优化，获得了Pareto最优解。研究结果表明：扭曲结构与内肋结构的耦合作用可诱导持续的二次流动，增强流体扰动并破坏热边界层，从而显著提升对流传热性能。当

为0.5 mm、

在3.6~3.9 mm以及

在50~70 mm范围时，可实现传热增强与流动阻力增长之间的良好平衡。

Abstract

To improve the heat transfer efficiency and overall performance of supercritical CO

（SCO

） gas coolers， a numerical study was conducted on the flow and heat-transfer characteristics of SCO

in internally ribbed twisted elliptical tubes. The heat transfer enhancement mechanism of the tubes was further analyzed based on the field synergy principle. The pitch （

）， rib height （

）， major semi-axis （

）， and Reynolds number （

） were used as design variables， and second-order response surface models for the Nusselt number， friction factor， and performance evaluation criterion were established using the response surface methodology （RSM）. Multi-objective optimization was then performed using the non-dominated sorting genetic algorithm II（NSGA-II） to obtain Pareto optimal solutions. The results suggest that the combined effects of the twisted geometry and internal ribs induce sustained secondary flows， enhance fluid mixing， and disrupt the thermal boundary layer， thereby significantly improving the convective heat transfer performance of the SCO

gas cooler. According to this study， a favorable balance between heat transfer enhancement and flow resistance increase can be achieved when

is 0.5 mm，

ranges from 3.6 to 3.9 mm， and

lies

within 50 to 70 mm.
