A diffusion flux principle of mass conservation was used for mathematical modeling of sand core coating process. A Galerkin method with linear axisymmetric square finite elements was used to solve the problem. It is shown that the coating thickness and the penetration depth increase with sand grain size. With increasing the apparent viscosity of the refractory coating slurry the coating thickness increases, but the penetration depth decreases linearly. A good agreement is found between the experimental data and numerical predictions.
