Dufour Effect on Transient MHD Double Convection Flow of Fractionalized Second-Grade Fluid with Caputo–Fabrizio Derivative

This article presents the problem, in which we study unsteady double convection flow of a magnetohydrodynamics (MHD) differential-type fluid presence heat source, Newtonian heating, and Dufour effect over an infinite vertical plate with fractional mass diffusion thermal transports. The constitutive equations for flux are modeled noninteger-order derivative Caputo–Fabrizio (CF) nonsingular kernel, respectively. Laplace transform inversion numerical algorithms used to derive analytical semianalytical solutions dimensionless concentration, temperature, velocity fields. Expressions skin friction rates transfer from noninteger integer orders, respectively, also determined. Furthermore, influence parameters ? id="M2"> ? on fields tabularly graphically underlined discussed. comparison between second-grade viscous fluids is depicted. It observed that integer-order have greater velocities than fluids. shows how affect flow.
