Solutions of the space-time fractional partial differential equations via fractional differential transforms
Abstract:
The main objective of this research is to solve fractional Chaffee-Infante, Equal-Width, Wu-Zhang and inhonogeneous nonlinear gas dynamic equations. The fractional Chaffee Infante and Equal-Width equations are solved by using
the two-dimensional fractional differential transform method (FDTM) and the modified fractional differential transform method (MFDTM) to find approximate solutions and using the modified fractional differential transform method (MFDTM) to solve the fractional Wu-Zhang system. After that, we use the differential transform method (DTM) and the reduced fractional differential transform method (RFDTM) to find approximate solutions of inhomogeneous fractional nonlinear gas dynamic equation. We compare FDTM and MFDTM solutions with the exact solution, calculate the relative error for fractional Chaffee-Infante equation and fractional Equal-Width equation. We compare the MFDTM solution with the exact solution, calculate the relative error for fractional Wu-Zhang system. vWe compare DTM and RFDTM solutions with the exact solution, calculate the absolute error and the absolute residual error for inhomogeneous fractional nonlinear gas dynamic equation. Finally, the Maple symbolic algebra program is used to plot the solutions of fractional Chaffee-Infante, Equal-Width, Wu-Zhang and inhomogeneous nonlinear gas dynamic equations.
