Cattaneo-Christov Model on Three-Dimensional Flow, Heat, and Mass Transfer of Prandtl Fluid over a Riga Plate

This paper examined the three-dimensional stretched flow, heat, and mass transport analysis of Prandtl fluid with the influences of chemical reactions over a Riga surface. This analysis is investigated in the presence of Catteneo-Cristov heat and mass fluxes. The resulting nonlinear models are simplified by appropriate similarity variables. The solutions of the reduced set of coupled equations are obtained numerically via the Chebyshev spectral collocation technique. The obtained numerical results were used to address and discuss the characteristics of flow, heat transfer, mass distribution, skin friction, Nusselt, and Sherwood numbers for various pertinent parameters. In addition, the validation of the present numerical scheme is achieved by comparing it with previous results obtained through other numerical results. It is noticed that the rate of heat and mass transfer escalate for the Prandtl parameter. Also, the thermal and mass distributions scale back with a high estimation of relaxation parameters. © 2023 Trans Tech Publications Ltd, Switzerland.
