| 内容記述 | Two-dimensional, time-dependent computational scheme has been devised for determining the flow development and the corresponding pressure drop in the entrance region of a circular pipe at the Reynolds numbers based on the pipe diameter of 10,100,2000,and 10000. An iterative, stream function-vorticity formulation was applied, utilizing a mesh system in which the axial grid size is nearly proportional to the Reynolds number. The velocity field, the pressure drop, and the convective and the viscous terms are compared with the experimental results and also with the previous analysis. Moreover, the effects of the Reynolds number and the superposed disturbances on the transition from laminar to turbulent flow were numerically simulated. | |||||||||
