Statistics-based method for determination of drag coefficient for nonlinear porous flow in calcareous sand soil
Generally, drag force applied by soil particles to seeping pore water is described as a type of body force in the form of hydraulic gradient I . For steady porous flow, the hydraulic gradient was widely formulated by the Forchheimer equation, containing two Forchheimer drag coefficients a and b . In...
