摘要:
基于高超声速预冷发动机闭式氦布雷顿循环中印刷电路板换热器(PCHE)的应用,对PCHE氢氦通道的热固耦合特性进行了数值研究,着重阐述了热侧氦参数对换热的影响机制。探究了热侧壁温和换热系数的变化特征及其对冷侧换热的影响。考察了通道截面温度和湍动能的分布情况。通过熵产和综合换热系数评价了PCHE通道的性能,进行了通道热应力分析,建立了热侧和冷侧换热关联式(误差在±15以内)。结果表明:热侧压力对换热仅有微弱影响; 热侧流量提高对热侧和冷侧换热均有增强作用。热侧进口温度下降导致热侧和冷侧换热减弱; 热侧进口温度提高造成通道熵产显著增加,热侧流量增加造成通道熵产显著减小; 高热应力出现在冷热流道之间和壁面两侧,局部最大热应力达到25 MPa。
Abstract:
Based on the application of printed circuit heat exchanger(PCHE)in the closed helium Brayton cycle of hypersonic precooled engine, the thermal-solid coupling characteristics of hydrogen-helium PCHE channel were numerically studied, and the effect mechanisms of hot-side helium parameters on heat transfer were emphatically expounded.The variation characteristics of hot-side wall temperature and heat transfer coefficient and the effect on cold-side heat transfer were investigated.The distributions of temperature and turbulent kinetic energy in channel cross-section were analyzed.The performance of PCHE channel was evaluated by the entropy generation and the comprehensive heat transfer coefficient, the thermal stress of channel was analyzed, and the heat transfer correlations of hot-side and cold-side were established(error within ±15).The results show that the hot-side pressure has only a weak effect on the heat transfer.The heat transfer of hot-side and cold-side is enhanced with the increase of hot-side mass flux.The decrease of hot-side inlet temperature causes the weakened heat transfer both of the hot-side and the cold-side.The increase of hot-side inlet temperature leads to the significant increase of channel entropy generation, and the increase of hot-side mass flux results in a significant decrease of entropy generation.High thermal stress occurs between the hot and cold flow channels and the side-walls, the maximum local thermal stress reaches 25 MPa.
