A new definition of fluctuation intensity was proposed to indicate the magnitude of flow disturbance enforced by the configuration and arrangement of slotted fin surface. The higher the fluctuation intensity,the larger the velocity gradient and the vorticity magnitude.
提出的新概念波动强度是表征翅片结构对流场扰动程度的物理量,波动强度越大,流场内的速度梯度、涡量强度越大,翅片结构对流场的扰动越大。
