Investigation on Jet Impinging Heat Transfer on Heated Surface in Vicinity of a Rotating Disk

  • 摘要: 采用数值计算方法模拟磨削工件表面的射流冲击对流换热过程,对不同旋转速度和旋转方向下,旋转盘诱导的气旋运动和射流冲击的耦合作用进行了研究分析。在转盘诱导的气旋流动影响下,冲击射流向转盘和加热表面之间区域的侵入能力受到抑制,但气旋流动与射流冲击的耦合作用均使得加热表面的对流换热能力相对圆盘静止时得到增强;盘缘在射流冲击喷嘴附近的切向速度与射流冲击方向协调时,旋转盘诱导的气旋运动和射流冲击的耦合作用有利于改善磨削弧区的对流换热,随着转盘旋转速度的增加,其强化对流换热的效果更显著。
