Abstract
The main aim and novelty of this numerical analysis is to investigate the thermodynamic features of magnetized Cattaneo–Christov heat and mass flux models on the radiative Casson fluid flow past a stretching cylinder manifested with the thermal and mass flow mechanism within the boundary layer regime qualitatively under the influence of Soret and Dufour effects. Pertaining to this numerical investigation, the primitive forms of produced nonlinear coupled partial differential equations are reduced to ordinary differential equations via similarity transformations and are solved by employing numerically efficient and stable Runge–Kutta fourth-order scheme. The graphical results for velocity, thermal and concentration fields, wall shear stress, Nusselt and Sherwood numbers are presented for the various values of parameters such as, 0≤K≤2.8, 0.1≤M≤2.3, 1.2≤β≤3.6, 0.1≤Du≤0.5, 0.1≤Ra,Q≤0.53, 0.4≤Sr≤0.8, 0.1≤Ec≤0.9, 0.1≤γ≤5, 0.1≤λ≤2.1 and 0.3≤Sc≤14. In addition, the produced numerical solutions indicate that, the higher curvature number suppressed the velocity and thermal fields. Elevating thermal relaxation number diminished the thermal energy distribution over a cylinder. Magnifying Lorentz forces decayed the flow velocity and enhanced the thermal field. Finally, a reasonable agreement between the current analysis and previously published results is tabularized.
