numerical solution of gas solution in a fluid‎: ‎fractional derivative model

A computational technique for solution of mathematical model of gas solution in a fluid is presented. this model describes the change of mass of the gas volume due to diffusion through the contact surface. an appropriate representation of the solution based on the müntz polynomials reduces its numerical treatment to the solution of a linear system of algebraic equations. numerical examples are given and discussed to illustrate the effectiveness of the proposed approach.
