摘要

摘要:
围绕紧凑型换热器内流动换热特性及高效计算方法进行研究，建立了基于多孔介质理论的紧凑型换热器温度分布快速计算方法。应用该方法，分别对参考ATREX发动机叉排管束预冷器构型和SABRE发动机渐开线螺旋排列管束预冷器构型的换热模型进行性能分析，建立了相应的传热性能快速计算的方法和流程，结果表明：预测结果与FLUENT 3D管束模型仿真结果一致，但耗时不足CFD仿真的1%，体现了快速算法在计算成本和速度方面的优势。

Abstract:
The research focused on the flow heat transfer characteristics and efficient calculation methods in compact heat exchangers. To achieve the research objectives, a fast calculation method for the temperature distribution of a compact heat exchanger based on the porous media theory was established. The heat transfer models of the staggered tube bundle of the pre-cooler configuration for the reference ATREX engine and the involute spiral tube bundle pre-cooler configuration for the SABRE engine were analyzed for performance, respectively. The corresponding methodology and procedure for rapid calculation of heat transfer performance were established. The results showed that the prediction results were consistent with the FLUENT 3D tube bundle model simulation results but the time consumed was less than 1% of CFD simulation. The advantages of the fast prediction method in terms of calculation cost and speed were demonstrated.
