The flow structure and thermal efficiency of a gas-droplet wall jet, injected through inclined holes into a transverse trench, is analyzed numerically. The predictions are carried out using three-dimensional RANS equations in the following ranges of two-phase flow parameters: initial droplet size d₁ = 0–20 µm and their mass fraction M_L1 = = 0–0.05. Gas turbulence is simulated using the model of Reynolds stress transport taking into account the two-phase character of the flow. The obtained simulation results are compared using the Eulerian and Lagrangian descriptions. The applicability of both approaches to describing the dynamics and heat transfer of a two-phase wall jet is shown.

数值分析了通过倾斜孔注入横向沟槽的液滴壁射流的流动结构和热效率。在以下两相流参数范围内，使用三维RANS方程进行预测：初始液滴尺寸d ₁ = 0–20 µm，质量分数M _L1 = = 0–0.05。考虑到流动的两相特性，使用雷诺应力传输模型模拟了气体湍流。使用欧拉和拉格朗日描述对获得的仿真结果进行比较。显示了两种方法在描述两相壁射流的动力学和热传递方面的适用性。
