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

Abstract

‎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 M"{u}ntz 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.
