The effect of soret and mass flow in a double-diffusive analysis of Maxwell fluid flow through a horizontal porous layer

The influence of the Soret and mass flow effect on a Maxwell fluid flow has been examined numerically. The stability of the flow of a Maxwell fluid in a horizontal porous layer that is heated and salted is being investigated for its linear stability. By resolving the eigenvalue problem, it can determine the wave number, critical Rayleigh number, and different flow properties over stability. Using linear stability analysis, the combined impact of the Soret effect and mass effect is examined for a better understanding of flow motion. Applying the shooting Runga-Kutta methods, these thermal and Solutel gradients are assessed. With consideration for Soret and mass effects, the nature of steady-state velocity, temperature and concentration profiles are also explored.
