Fractional natural decomposition method for solving fractional system of nonlinear equations of unsteady flow of a polytropic gas
In this paper, we apply the fractional natural decomposition method suggested by M. S. Rawashdeh et al. in  to derive approximate analytical solutions to system of nonlinear equations of unsteady flow of a polytropic gas with time-fractional derivatives. The proposed method (FNDM) has been applied successfully to solve this system. So, the results re-confirm that this method is very efficient and accurate to solve others nonlinear systems problems.
