【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倾斜正浮力射流进行了数值计算,成功模拟了端涡现象及其发展过程,比较了倾角为60°倾斜浮力射流与垂直浮力射流轨迹线上的温度和稀释度,还得出了浮力射流是否发生贴壁现象的界限值。更多还原

【Abstract】 Using the Hybrid Finite Analytic Method (HFAM) and staggered grid, the authors treat numerically the finite length inclined positively buoyant jets in cross flows and simulate the phenomena and development of the end-vortices successfully. The temperature and dilution on the trajectory of jets at angles of 60 and 90°to the horizontal are compared .And the limiting value that whether the 60° inclination jets touch the wall or not is given.更多还原
