瞬变流透气率;瞬时流动透气性
Under the assumption that the permeability varies with the piecewise experimental law of the pressure drop, the equation for steady radial flow and the non-linear equation for transient flow through porous media were derived and solved.
本文基于渗透率随压力呈分段的指数变化规律,建立并求解了平面径向稳定渗流方程和非线性不稳定渗流方程。
