Analytical treatment of radiative Casson fluid over an isothermal inclined Riga surface with aspects of chemically reactive species

This article concerns an examination of thermal attributes generated in non-linearly varying viscosity-dependent viscoelastic fluid flowing over an isothermally inclined riga surface. The mathematical formulation is conceded by obliging conservation laws of momentum and energy in the form of PDE's. Thermal aspects are highlighted in the attendance of radiative heat flux. Similarity variables are capitalized for the transmutation of PDE's into ODE's. Analytical solution of attained differential setup is attained by employing Laplace transform technique. The influence of flow concerning variables on related distributions is divulged in a graphical manner. The variation in quantities of engineering interest like wall shear stress, thermal and mass variation on the surface is also measured. It is found that the accelerating parameter, chemical reaction parameter, positive modified Hartmann number, and radiation values improve skin friction while heat absorption parameter retards friction. Moreover, an increment in chemical reaction and heat absorption parameters causes a reduction in momentum distribution. (C) 2021 THE AUTHORS.
