摘要

摘要考虑了不可压缩流体在倾斜压力梯度条件下，在速度滑移边界条件下通过水平多孔通道的瞬态流动。流动是由沿流动方向的倾斜压力梯度引起的层流。建立了控制流动的方程，并利用拉普拉斯变换技术进行求解，得到了滑移边界条件下的半解析解。结果表明，随着滑移参数的增大，流动速度增大。

Transient Flow Through a Porous Channel with Ramped Pressure Gradient and Velocity Slip Boundary Condition

Abstract A transient flow formation of an incompressible fluid through a horizontal porous channel assuming a ramped pressure gradient is considered with the velocity slip boundary conditions. The flow is a laminar flow caused by ramped pressure gradient along the flow direction. The equation governing the flow is modeled, and solved by the Laplace transformation technique to obtain a semi-analytical solution under slip boundary conditions. It was noted that the flow velocity increases as the slip parameter is increased.
