为分析缠绕管式换热器关键几何结构对其流动和传热性能的影响
采用多目标遗传优化算法对壳侧的流动和传热特性进行了数值模拟研究
并对通过中心复合设计得出的实验点进行了计算。研究结果表明:缠绕管式换热器的壳侧压降随着层间距、缠绕角、同层管间距的增大而减小; 壳侧换热系数随着层间距的增大而减小
随着管外径的增大而增大
随着螺旋角的增大先增大后减小。通过敏感度分析可知:螺旋角和层间距对缠绕管式换热器的流动和传热性能影响最大
在计算工况下
层间距对压降和换热系数都呈负相关; 螺旋角与压降呈负相关
与换热系数呈正相关。同时
应用多目标遗传算法在连续响应面的基础上对原结构进行优化
得到3组优化结果
换热系数平均增加了2.93%
压降平均降低了40.27%
综合传热性能均好于原结构。该研究成果可为缠绕管式换热器的优化设计提供理论基础。
Combining multi-objective optimization and numerical simulation
the effects of the key structural parameters of a spiral wound heat exchanger on its flow and heat transfer characteristics were studied. And the simulation groups generated by central composite design were calculated. Simulation results show that the shell-side pressure drop of the spiral wound heat exchanger decreases with the increase of the layer pitch
spiral angle and tube pitch; the shell-side heat transfer coefficient of the spiral heat exchanger decreases with the increase of the layer pitch and increases with the external diameter of the tube
however the coefficient increases firstly with the spiral angle then decreases. The sensitivity analysis also shows that the shell-side flow and heat transfer characteristics are most affected by the spiral angle. Under the working conditions
both pressure drop and heat transfer coefficient are negatively correlated with the layer pitch
and the spiral angle is negatively correlated with the pressure drop but positively correlated with the heat transfer coefficient. Three sets of optimal results were obtained by employing multi-objective genetic algorithm to minimize the shell-side pressure drop and maximize the heat transfer coefficient on successive response surfaces. Compared with the original group
the average heat transfer coefficient is increased by 2.93% while the average pressure drop is reduced by 40.27%
which is of great significance for the study of spiral wound heat exchanger.
