Thermal analysis for radiative flow of Darcy–Forchheimer nanomaterials subject to entropy generation

Abstract Background and objective Flow due to the Darcy–Forchheimer medium is an important perspective in various geophysics, industrial processes, geothermal energy, thermodynamic processes. The importance of noticed technical, mechanical, industrial, scientific fields including atomic waste archive, artificial dialysis, catalytic converters, gas turbine, improved oil recuperation, atherosclerosis, grain stockpiling, geo-energy production, warm protection designing, etc. In view such applications, this paper highlight influence entropy generation chemical reactive MHD (magnetohydrodynamic) nanoliquid flow with radiation. by exponentially stretching permeable sheet taken. Thermal radiation, heat source, magnetic force, dissipation impacts are considered thermal expression. Additionally, Buongiorno’s model random thermophoresis diffusions explained. Physical features deliberated. first-order isothermal reaction discussed. Methodology Non-linear expressions reduced dimensionless non-linear system through implementation non-similar transformations. resultant systems solved subject local non-similarity via ND-solve technique Results Graphical results for rate, concentration, velocity, field versus emerging variables studied. reverse trend holds velocity variable. A larger approximation Eckert number intensifies field. Conclusions higher Forchheimer reduces fluid flow. impact concentration seen motion Similar behavior distribution radiation effects. porosity variable declines while effect Brinkman number. diffusion increases generation.
