摘要

摘要: 研究可渗透收缩薄膜上的不稳定粘性流动．通过相似变换得到相似方程．在不同的不稳定参数、质量吸入参数、收缩参数、Prandtl数下，数值地求解相似方程，得到速度和温度的分布，以及表面摩擦因数和Nusselt数等．结果发现，与不稳定的伸展薄膜不同，在质量吸入参数和不稳定参数的某一范围内，可渗透收缩薄膜上的不稳定流动存在双重解．

Abstract: The unsteady viscous flow over a continuously permeable shrinking surface was studied. Similarity equations were obtained through the application of similarity transformation techniques. Numerical techniques were used to solve the similarity equations for different values of the unsteadiness parameter, the mass suction parameter,the shrinking parameter and Prandtl number on the velocity and temperature profiles as well as the skin friction coefficient and the Nusselt number. Different from an unsteady stretching sheet,it is found that dual solutions exist for a certain range of mass suction and unsteadiness parameters.
