涡量传递理论分子式:CAS号:性质:在湍流运动的流体中,众多的流体微团都在进行不规则的运动,这和气体分子的不规则热运动非常类似。如果令湍流运动中流体微团的速度与气体分子的运动速度相对应时,则可获得与平均自由程相当的混合长度的概念。混合长度可以被认为是流体微团能够保持其原有速度不变而被传递的最长距离(混合长度的概念不但可以应用于动量传递之中,也可以应用于热量传递和质量传递之中)。Taylor曾经将被传递的量视为涡量(vorticity)而提出一个涡量传递理论。如果考虑一个x-y平面二维流动,沿x方向上的时均流速为ux,产生的剪应力为τyx,则根据涡量传递理论,τyx可表示为: τyx=1/2ρι2|dux/dy|-dux/dyρ为流体密度;l为混合长。
