The study investigates heat and mass diffusion in 2D Cross nanofluid flow over a parabolic surface using the Cattaneo-Christov model, considering temperature-dependent viscosity, enthalpy change, and activation energy. The determining equations are generated in the form of PDEs and transformed into ODEs using similarity transformations, and numerical outcomes are analyzed using the BVp4c method in Matlab software. The velocity of fluid shows reverse results with increasing Weissenberg number and viscosity parameter, while larger values of thermal and concentration relaxation parameters indicate a decrease in the respective fields. Numerical results for skin friction coefficient, Sherwood number, and Nusselt number for various parameters are presented in tables.
The existing study investigates the heat and mass diffusion by using Cattaneo-Christov model for the boundary layer 2D Cross nanofluid flow over the surface of parabola along with temperature dependent viscsoity. Furthermore current problem is extended by taking the influence of enthalpy change and activation energy. Instigate from above assumptions the determining equations are generated in the form of PDEs and turned down into ODEs by using similarity transformations. A well-known method (BVp4c) is introduced to scrutinize the numerical outcomes and graphical behavior by Matlab software. The velocity of fluid displays reverse results for the enhancement in Weissenberg number and viscosity parameter. A larger value of thermal and concentration relaxation parameter indicates the fall in the respective fields. Numerical outcomes of skin friction coefficient, Sherwood number and Nusselt number for numerous parameters are shown in tables.
