项目摘要
It was found by the simultaneous measurements on the velocity and concentration fields of matter that a round jet injected into a counter uniform flow possessed strong mixing ability. Time-delayed measurements between the velocity field in an axisymmetrical plane and the concentration field in a cross-sectional plane of the jet were also conducted to elucidate the physical mechanism causing the jet wandering. Furthermore, the flip-flop jet which has a similar jet wandering as the counter-jet was investigated numerically. The mult-igrid method, together with parallelization, was incorporated in numerical analysis to accelerate the calculation speed. The simulated flow showed a jet wandering matching quantitatively with the experimental results, confirming the validity of the calculation method.
通过对物质速度场和浓度场的同时测量,发现圆形射流喷入反向均匀流中具有很强的混合能力。通过对轴对称平面内速度场和射流横截面内浓度场的延时测量,阐明了射流漂移的物理机制。此外,数值研究了具有与反向射流相似的射流漂移的触发射流。在数值分析中采用多重网格法,并结合并行化技术,加快了计算速度。数值模拟结果与实验结果吻合较好,验证了计算方法的正确性。
