摘要/Abstract

摘要： 针对具有相同相对曲率（d/D=0.1）的凹形和凸形半圆柱靶面，在典型的雷诺数（Re=5 000~12 000）和无因次冲击距离（H/d=1~8）下进行了射流冲击对流换热的实验研究，同时在特定的射流雷诺数下进行了射流冲击大涡模拟分析，以揭示冠齿喷管在不同形状靶面上的强化传热作用机制。研究结果表明：射流喷管和靶面形状对于射流驻点附近的流场和对流换热具有显著的影响，冠齿喷管出口诱导的流向涡改变了圆形射流发展中的轴对称环形涡内在特征，无论是凹形还是凸形靶面，冠齿喷管相对于圆形喷管都体现出一定的强化射流传热效果；与凸形靶面相比，射流冲击凹形靶面受到凹腔内部的回流影响，导致冠齿喷管射流冲击对流换热的降低。

Abstract: An experimental research is performed to illustrate the different mechanisms of the chevron nozzle in improving jet impingement heat transfer over concave and convex semi-circular target surfaces with the same relative curvature (d/D) of 0.1. The experimental tests are carried out with jet Reynolds numbers (Re) ranging from 5 000 to 12 000 and dimensionless nozzle-to-surface distances (H/d) ranging from 1 to 8. Simultaneously, computations based on the large eddy simulation approach are conducted with a specific jet Reynolds number to characterize the flow dynamics of the chevron jet impingement on the different target surfaces. Results show that both the nozzle shape and the target surface shape significantly affect the jet flow dynamics and heat transfer in the vicinity of jet stagnation. For the chevron nozzle, the streamwise vortices developed from the chevron notches change the vortical coherence of the axisymmetric toroidal vortices in the round jet development. Despite of the target surface shape, the chevron nozzle is confirmed to be capable of enhancing the jet impingement heat transfer related to the round nozzle. Compared to that on the convex surface, the jet impingement on the concave surface is affected by the recirculation flow inside the concave cavity, leading to a degradation of chevron-nozzle jet impingement heat transfer, particularly at large nozzle-to-surface distances.

Key words: jet impingement, chevron nozzles, concave target surface, convex target surface, convective heat transfer
