Abstract
This work studies the analysis of heat mass transfer of generalized second grade fluid. The problem is modelled using Caputo-Fabrizio fractional derivative approach. The effects of MHD, chemical reaction, heat source and porous media are also included. The infinite vertical plate is subjected to the phenomenon of exponential heating. The governing equations along with their corresponding initial and boundary conditions are transformed into non-dimensional form. The system of governing equations has been solved through Laplace transform. Plots are prepared for several physical parameters of interested and discussed in detail. In limiting sense, the published results are recovered analytically and a comparison is made which shows an excellent agreement.
