摘 要:
在考虑瞬态过程中动量扩散速度基础上,用拉普拉斯变换法对无限长平板突然起动瞬态动量定解方程进行了求解,并按涡量定义求出涡量分布函数。结果表明:伴随动量扩散的波动性,涡量扩散也存在波动性。

摘 要:
Based on the limited momentum propagation velocity, this paper presents the solution of the transient momentum equation by laplace transform. The distribution functions of velocity and eddy are given. The results show that eddy diffuses in the certain velocity in the viscous fluids, accompanying with momentum wavery propagation.
