摘要

蒸汽喷射器是喷射式制冷系统的关键设备，具有节能环保优势。同时考虑三维和非平衡凝结效应，优化、验证并对比了蒸汽喷射器模型。对比了考虑凝结效应的优化模型与理想气体模型的模拟结果。基于该凝结模型，研究了湍流处理方法（雷诺平均方法和大涡模拟方法）对模拟结果的影响。分析了不同模型捕捉到的非平衡凝结、激波等复杂流动现象。结果表明：优化后的蒸汽喷射器模型可以以最低计算成本可靠预测喷射器性能并捕捉其内部复杂流动现象，其中大涡模拟方法得到的最大液体质量分数低于雷诺平均方法，喷射系数与实验值的最大相对误差为11%；与理想气体模型相比，凝结模型可使喷射系数和临界出口压力与实验值之间的平均相对误差分别降低72.0%和29.9%。

Abstract

Steam ejectors are vital components of ejector refrigeration systems and have attracted considerable attention owing to their energy savings and environmental protection. In this study

steam ejector models were optimized

validated

and compared by considering the three-dimensional and non-equilibrium condensation effects. The simulation results of the optimization model were compared with those of the ideal gas model. Based on the condensation model

the effects of the turbulence models (Reynolds-averaged Navier-Stokes (RANS) and large eddy simulation methods (LES)) on the simulation results were studied. Complex flow phenomena captured by different models

such as shock waves

non-equilibrium condensation

and boundary layer separation

were compared and analyzed. The results show that the optimized steam ejector model can credibly predict the ejector performance and capture the complex flow phenomena inside the ejector at the lowest computational cost. The maximum liquid mass fraction obtained using the large eddy simulation method is lower than that obtained using the Reynolds-averaged Navier-Stokes method. The maximum relative deviation against experiments of the entrainment ratio was obtained using the large eddy simulation method of 11%. The condensation model reduces the average relative deviations of the entrainment ratio and critical discharge pressure by 72.0% and 29.9%

respectively.
