This study discusses the magnetohydrodynamics flow of Oldroyd-B fluid on a rotating disk, considering the influence of thermophoresis on particle deposition and the Soret-Dufour effects. Numerical results obtained through the von Karman transformation and BVP Midrich technique in Maple show that axial thermophoretic velocity increases with the enlargement of relative temperature difference parameter and thermophoretic coefficient.
In this study, an investigation of magnetohydrodynamics flow of Oldroyd-B fluid by a rotating disk with the influence of thermophoresis on the deposition of particles is discussed. Additionally, the Soret-Dufour effects are taken into consideration. The von Karman transformation is used and the numerical results are obtained through BVP Midrich technique in Maple. The results are given through graphical structure and tabular form. The solutions of the governing equations are obtained and presented graphically in the form of velocity fields, temperature and concentration distributions. The results of local Stanton number (or inward axial thermophoretic deposition velocity) are presented through table. Results reveal that axial thermophoretic velocity enhances with the enlargement of relative temperature difference parameter and thermophoretic coefficient.
