Numerical investigation of thermal enhancement using MoS2–Ag/C2H6O2 in Prandtl fluid with Soret and Dufour effects across a vertical sheet

Due to numerous applications, the study of hybrid nanofluids is a hot topic of research, which enables us to improve thermal performance. The current work is carried out to inspect thermal and solutal transportation in the Prandtl model toward a heated stretched plate. The flow analysis has been developed in Cartesian coordinates considering variable thermal conductivity and non-uniform diffusion coefficient. Furthermore, the modeling of physical phenomena is carried out considering the porous stretched surface under Soret and Dufour effects and heat generation. The principle of boundary layer theory was used to simplify the model partial differential equations (PDEs). The derived PDEs have been transformed into a set of coupled nonlinear ordinary differential equations (ODEs) after utilizing the appropriate transformation. The converted ODEs are coupled and nonlinear. So, the exact solution is not possible. Thus, the derived ODEs have been solved numerically via the finite element scheme. The impact of numerous emerging parameters have been displayed and explained by observing the underlying physics behind them. Moreover, a comparative study is also established. A grid independent survey is established for the convergence of the used numerical approach.
