APPLICATION OF LOCAL MESHLESS METHOD FOR THE SOLUTION OF TWO TERM TIME FRACTIONAL-ORDER MULTI-DIMENSIONAL PDE ARISING IN HEAT AND MASS TRANSFER

ABSTRACT
In this article, we presented an efficient local meshless method for the numerical treatment of two term time fractional-order multi-dimensional diffusion PDE. The demand of meshless techniques increment because of its meshless nature and simplicity of usage in higher dimensions. This technique approximates the solu­tion on set of uniform and scattered nodes. The space derivatives of the models are discretized by the proposed meshless procedure though the time fractional part is discretized by Liouville-Caputo fractional derivative. The numerical re­sults are obtained for 1-, 2- and 3-D cases on rectangular and non-rectangular computational domains which verify the validity, efficiency and accuracy of the method.
