摘　　要：本文利用混合有限分析法及交错网格的思想 ,对横流中有限长线源型浮力射流进行数值计算 ,成功模拟了端涡现象及其发展过程 。Using the hybrid finite analytic method and staggered grid, the authors treated numerically the line buoyant jets in cross flows and simulated the phenomena and development of end vortices successfully. The influences of diffuser length on turbulent buoyant jets were analyzed.
