摘要: Abstract Gillespie's model for the kinetics of radial spreading a finite liquid reservoir in thin porous substrate is corrected to properly account time dependence position advancing meniscus. A similarity solution volume fraction within obtained using power-law expressions permeability and capillary pressure on fraction. It shown that asymptotic rate at long times independent initial conditions.
