Application of modern approach of Caputo-Fabrizio fractional derivative to MHD second grade fluid through oscillating porous plate with heat and mass transfer

Abstract

In this research paper, we analyze the flow characteristics of magnetohydrodynamic second grade fluid with heat and mass transfer embedded in porous medium. The modeling of partial differential equations governs the flow have been established with modern approach of Caputo-Fabrizio fractional operator (). The partial differential equations of noninteger order derivatives have been solved by invoking Laplace and Fourier sine transforms. The new analytic solutions for temperature, concentration and velocity are investigated and expressed in terms of simple elementary functions. The corresponding general solutions have been particularized with and without magnetic field and porous medium for the classical Newtonian and second grade fluids as the limiting cases of our general results. The effects of the embedded physical and geometric parameters have been depicted through graphs for velocity, temperature and concentration respectively. The graphical results show several physical discrepancies and analogies on the fluid flow. Finally, our results suggest that increasing the Grashof number, heat transfer due to convection facilitates the flow velocity profile and an opposite trend is observed in thermal Grashof number as well.

“…Abro et al [25] analytically studied MHD Jeffery fluid under the impact of thermal radiation. The others related works can be studied Khan [26][27][28][29][30][31]. Dawar et al [32] examined Eyring-Powell fluid flow under the impact of thermal radiation over a porous medium.…”

Mathematical analysis of memristor through fractal‐fractional differential operators: A numerical study

“…They claimed that new strange behaviors of the attractors were not possible by only classical differentiations. In short, the study can be continued for the charming and effective role of fractional calculus in applied engineering problems, 20–31 but we include here recent attempt in categorically as epidemiology, 32–39 heat and mass transfer, 40–44 fluid mechanics, 45–47 nanofluids, 48–51 and electrical engineering 52–55 . Motivating by above discussion, our aim is to propose the controlling analysis and coexisting attractors provided by memristor through highly nonlinear for mathematical relationships of governing differential equations.…”

Numerical and mathematical analysis of induction motor by means of AB–fractal–fractional differentiation actuated by drilling system

“…They discussed novel solutions for the mathematical model of free convection flow of nanofluid via special functions so called Mittag-Leffler and M-functions. In this continuity, the studies can be continued on the theory of fractional calculus but we end here categorically as role of fractional calculus in induction machines and electrical engineering [23][24][25][26][27][28], role of fractional calculus in epidemiological diseases [29,30], role of fractional calculus in fluids and nanofluids [31][32][33][34][35], role of fractional calculus in heat transfer through nanoparticles [36][37][38], and role of fractional calculus in magnetohydrodynamics and porosity [39,40]. Additionally, the different dynamical studies with and without fractional differential operators can be studied [41][42][43][44][45][46][47][48][49].…”
