| Abstract: | A new general numerical integration method for burning surface calculation of three dimensional grain has been developed on the basis of the previous general numerical differentiation. The new scheme computes the grain burning surface directly. Its use eliminates the arbitrariness of computation result because of different web thickness interal and the source of potential error that was present in the previous method. Comparison of the new method with the old one and analytical solutions shows that the developed method is more efficent and accurate. |
