Heat and mass transport of MHD viscoelastic fluid flow towards a permeable stretching cylinder

Abstract

Heat and mass transport of MHD flow of viscoelastic Maxwell fluid due to a stretching cylinder on a porous medium with the impact of curvature parameter, Schmidt number, Deborah number and chemical reaction are investigated. Radiation, MHD, Brownian motion and thermophoresis effects are also considered for modelling. A set of (PDEs) partial differential equations was used to define the mathematical description of the flow. These equations were turned into nonlinear (ODEs) ordinary differential equations via similarity transformations. Since these PDEs are challenging to solve via the analytical method, we compute the solutions using the RK45 technique using inbuilt software bvp4c. This article's critical findings and novelty present the answers for the various physical parameters in two distinct geometries; among them, one represents the cylinder (curvature parameter αc = 1), and other represents the horizontal plate (curvature parameter αc = 0). The Maxwell fluid parameter elevates the temperature and concentration contour for both the plate and cylinder. Further, the velocity of the viscoelastic fluid displays inconsistent behaviour for the Deborah number and curvature parameter. In addition, we compared the acquired numerical result to existing work and discovered that the current numerical results are in remarkable agreement.
