摘要
为研究大热流背景下不同结构参数对蜂窝板传热和阻力性能的综合影响,基于ANSYS Workbench平台的目标驱动优化系统,对蜂窝板进行数值建模,并采用中心组合设计优化算法对其进行场态分析和多目标优化。结果表明:流体在蜂窝板内的流动传热呈周期性变化,流经焊点时受到强烈扰动并生成射流与小旋涡,能有效强化传热;鼓胀高度H对传热和阻力性能的影响最大,焊点直径D次之,焊点间距L的影响最小。通过优化计算最终得到了3组较优的结构参数搭配,可为蜂窝板的优化设计提供参考。
In order to study the comprehensive impact of different structural parameters on the heat transfer and resistance performance of honeycomb plate under large heat flow,a numerical modeling of honeycomb plate was constructed under the frame of target-driven optimization system based on the ANSYS Workbench platform.And a central composite design optimization algorithm was used to analyze the flow field and to implement multi-objective optimization.The results show that the flow and heat transfer of fluid in honeycomb plate exhibits periodic changes.The fluid is strongly disturbed and generated jets and small eddies when flowing through the solder joints,which could effectively strengthen the heat transfer.It can be concluded that the bulge height H has the greatest impact on heat transfer and resistance performance;the next important factor is the solder joint diameter D,while the solder joint spacing L has the smallest impact.Through optimization calculation,three groups of superior structural parameters are obtained,which may provide a reference for the optimal design of honeycomb plate.
