A numerical method based on the finite volume method for solving Fokker-Planck equation was developed to simulate the fiber orientation distribution of fiber suspensions flowing through a curved expansion duct.
Richards equation, as shown by Philip (1969), is essentially a nonlinear Fokker-Planck equation (FP):
