Computer program which simulates the unidirectional slip casting process has been developed. The equation used to calculate the dewatering rate is derived based on Darcys law and the Carman-Kozeny equation. This obtainted equation can calculate the dewatering rate through a porous material composed of many layers with different particle packing densities. As an another program feature, the particle packing density of the slip cast layer is correlated to the dewatering rate. First the dewatering rate is calculated through the first element, and next the density of the second element is predicted. Slip casting process can be simulated by repeating such calculations. This program also calculates the casting pressure which provides each element with a predetermined particle packing density by controlling the dewatering rate.
