Abstract A variety of reactive structures containing chemical reactions in the process of combustion, biochemical frames, and catalysis are homogeneous-heterogeneous (H-HR). Besides, chemical reactions are used as part of applications such as hydrometallurgical industries of food manufacturing, dispersion and forming fog, manufacture of polymers and ceramics. The purpose of the current study is to examine H-HR in the MHD flow of a non-Newtonian Prandtl fluid past a permeable linear horizontal expandable (shrinkable) surface in the Darcy-Forchheimer scheme of porous material. The thermal features under thermal radiation and heat generation (absorption) impact are taken into account. The leading partial-differential equations with appropriate boundary conditions are solved by Chebyshev spectral collection technique (CSCT) and the Runge-Kutta-Fehlberg technique (RKF45). Impacts of some significant parameters on the velocity of the flow, energy, and concentration profiles are graphically measured. Comparing with two techniques and with previous literature, which demonstrates the feasibility of the present numerical solution, are compatible with the findings gained from the restrictive status of the current system. The main outcomes are the heat transport rate at the surface is improved with the higher parameter values of thermal radiation and suction (blowing). The effect of porous Darcy-Forchheimer material is a thermal conductor that disperses the thermal energy of the system more competently.
