Abstract
Continuity equations and Darcy''s law are utilized to obtain a basic equation for cake filtration. The boundary condition at the moving surface is newly derived, and the cake filtration is formulated in a Stefan problem.
A similarity variable is introduced to transform the governing equation into an ordinary one, which in turn is solved numerically. The moment method is shown to offer good initial values to start the numerical computation.
Satisfactory agreement is observed between experimental data of Shirato et al. and computed values of some physical properties.
