“…In Figure 1, the geometry of problem is clearly demonstrated. Thus, having all aforementioned physical assumptions, the partial differential equations that define the flow problem are given as follows (Endalew and Nayak 24 and Endalew et al 26 ):

\frac{\partial w}{\partial t'} = ν \frac{\partial^{2} w}{\partial {y'}^{2}} - (\frac{σ B_{o}^{2} \sin^{2} ϕ}{ρ} + \frac{ν}{{K'}_{normalp}}) w + (\cos γ) g β' (C' - {C'}_{\infty}) + (\cos γ) g β (T' - {T'}_{\infty}),

ρ C_{p} \frac{\partial T'}{\partial t'} = - \frac{\partial q_{r}}{\partial y'} + κ \frac{\partial^{2} T'}{\partial {y'}^{2}} + S' (T' - {T'}_{\infty}),

\frac{\partial C'}{\partial t'} = D \frac{\partial^{2} C'}{\partial {y'}^{2}} - K_{c} (C' - {C'}_{\infty}) .

An exact analysis of a radiative hydromagnetic flow behavior over a tilted parabolic plate through a permeable medium along with variable species concentration and fluid temperature in the presence of a slanted magnetic field parameter, chemical reaction, and heat generation has been carried out in this study. Closed‐form analytical benchmark solutions for flow‐governing equations are obtained by using the Laplace transform method. Thereafter, the incidences of different important physical entities on the nondimensional velocity field, temperature distribution, and species concentration are presented using graphs, whereas impacts of various physical entities on wall shear stress, heat and mass transfer rates are presented in tables. It is worth noting that an increase in the magnetic field and its inclination angle causes the reduction in the fluid velocity. However, wall shear stress increases with the increase of magnetic field and its inclination angle. The novel results in this article can be used to improve quicker cooling and producing miniaturized heat flow systems with upgraded efficiency and cost‐effectiveness.

In this study, the impacts of heat and mass transfer characteristics on an isotropic incompressible Casson fluid flow over an oscillatory plate with the incidences of solutal and thermal boundary conditions have been investigated. Exact solutions of the fundamental equations governing the fluid flow are determined by using the Laplace transform technique. Numerical results based on analytical solutions are presented in graphical and tabular illustrations to clarify the behaviors of the fluid. Most interestingly, both fluid velocity and species concentration increase with an increment of mass transfer coefficient, whereas the fluid velocity diminishes as oscillating frequency increases near the surface of the plate. This happens due to the presence of high fluctuation of the plate in the flow system. Finally, this investigation is helpful to the scientific community, and the obtained results can be used as benchmark solutions for solving nonlinear flow governing problems fully via various numerical methods.

In the current article, we examine the slip effects for the inclined MHD Williamson fluid over a permeable wall with a chemical reaction. The second law of thermodynamics was applied to examine the aspects of entropy generation. The governing partial differential equations (PDEs) are reduced to ordinary differential equations (ODEs) via appropriately adjusted transformation. The dimensionless developed boundary layer equations have been solved by differential transform method (DTM) for various values of parameters. The most relevant outcomes of the current analysis are that augmented magnetic strength and Williamson fluid parameter undermine the fluid velocity which established a thicker velocity boundary layer while suction/injection show the opposite trend. Another most important outcome is that an increase in suction/injection decreases the entropy generation while it uplifts with Brinkman number. It is also observed that Bejan number decreases with the chemical reaction parameter.
