Numerical investigation of mixed convective Williamson nanofluid flow over a stretching/shrinking wedge in the presence of chemical reaction parameter and liquid hydrogen diffusion

Abstract

The numerical simulation of mixed convective Williamson nanofluid flow over a stretching/shrinking wedge with chemical reaction parameters and liquid hydrogen diffusion is studied. The usage of Williamson fluid in industry has had a considerable impact on industrial processes. Chemical reactions substantially impact heat and mass transfer in hydrometallurgical industries and chemical technology. The governing equations of the inquiry are nonlinear partial differential equations with surface constraints. The similarity transformation transforms partial differential equations into nondimensional ordinary differential equations that may be solved with the MATLAB bvp5c function. Variations in nanofluid velocity, temperature, and concentration patterns are graphically represented and thoroughly examined. In the case of a stretching/shrinking wedge, the liquid velocity decreases as the Williamson nanofluid parameter values increase. The dual nature solution for the skin friction coefficient is obtained when the Williamson nanofluid parameter increases. The liquid’s temperature rises proportionately to the thermophoresis and Williamson nanofluid parameters. As the Schmidt number increases, the fluid concentration improves while the chemical reaction parameter decreases.
