Capillary Pressure LAMBDA Functions

Brooks-Corey capillary pressure, [kPa]. Pc = Pd × Se^(-1/λ) (SI units).

Brooks-Corey saturation from capillary pressure, [fraction]. Inverse of Pc function (SI units).

Van Genuchten capillary pressure, [kPa]. Se = [1 + (αPc)^n]^(-m) (SI units).

Van Genuchten saturation from capillary pressure, [fraction]. Inverse of Pc function (SI units).

Leverett J-function, [dimensionless]. J = (Pc/σcosθ) × √(k/φ) (SI units).

Capillary pressure from J-function, [kPa]. Pc = J × σcosθ × √(φ/k) (SI units).
