【摘要】 通过有限元法对直角弯管流道流场进行数值模拟,给出了直角弯管的速度、流线、压力可视化图像,以及直角弯管内流体流动时涡旋产生的位置和大小情况,绘出了进油口速度与进出油口两端压力差之间的关系曲线以及直角弯管内直管的摩擦阻力系数与雷诺数之间的关系曲线。更多还原

【Abstract】 The flow fluid in the angle pipe is simulated,and the visualization images of velocity,streamline and pressure are shown.The location and size of vortexes are determined in the right angle pipe.The curve indicating the relationship between inlet velocity and pressure loss and the curve representing the relationship between Reynolds number and pipe friction coefficient in the right angle pipe are drawn.更多还原
