摘 要: | 本文对径向湍流自由射流作了计算,研究了边界条件的不同取法对计算结果的影响,与文献发表的计算结果和实验结果作了比较,再次证明上游湍流结构的边界条件对射流的渐近扩张速率及雷诺应力等流场参数有明显的影响.

COMPUTATION OF RADIAL JET AND THE EFFECTS OF THE BOUNDARY CONDITIONS |
| |
Abstract: | A radial turbulent jet has been computed with different boundary condition used, also compared with the experimental data of the reference. It is checked again that the upstream conditions of the turbulence structure has obvious effect to the spreading rate of the jet and other flow field characters. |
