In this paper, a novel technique is formed to obtain the solution of a fractional gas dynamics equation. Some reproducing kernel Hilbert spaces are defined.Reproducing kernel functions of these spaces have been found. Some numerical examples are shown to confirm the efficiency of the reproducing kernel Hilbert space method. The accurate pulchritude of the paper is arisen in its strong implementation of Caputo fractional order time derivative on the classical equations with the success of the highly accurate solutions by the series solutions. Reproducing kernel Hilbert space method is actually capable of reducing the size of the numerical work. Numerical results for different particular cases of the equations are given in the numerical section. KEYWORDS fractional gas dynamics equation, Hilbert space, operators
MSC CLASSIFICATION46E22; 34A08 Recently, many numerical methods have been implemented to solve fractional differential equations. These techniques are Adomian decomposition method, 17 homotopy analysis method, 18 homotopy perturbation method, 19 and variational iteration method. 20 Singh et al 21 investigated the fractional partial differential equations showing up in biological populations. Generalized differential transform method has been implemented to search the solution of time-fractional reaction diffusion equations. 22 Singh et al 23 have investigated many nonlinear fractional differential equations. Bhrawy et al 24 have applied the operational matrix concept for solving the fractional diffusion equations. Machado et al 25 and Yang et al 26 have implemented local fractional series method to investigate fractional differential equations.
