This paper deals with approximating the time fractional Tricomi-type model in the sense of the Caputo derivative. The model is often adopted for describing the anomalous process of nearly sonic speed gas dynamics. The temporal semi-discretization is computed via a finite difference algorithm, while[r]

The aim of this work is to present numerical treatments to a complex order fractional nonlinear onedimensional problem of Burgers’ equations. A new parameter rt is presented in order to be consistent with the physical model problem. This parameter characterizes the existence of fractional structures[r]

Calculus of Finite Differences3.1. INTRODUCTIONFinite differences: The calculus of finite differences deals with the changes that take place in thevalue of the dependent variable due to finite changes in the independent variable from this westudy the relations that exist between[r]

We propose a new monotone finite-difference scheme for the second-order local approximation on a nonuniform grid that approximates the Dirichlet initial boundary value problem (IBVP) for the quasi-linear convection-diffusion equation with unbounded nonlinearity, namely, for the Gamma equation obtain[r]
