In this research, double-diffusive nonlinear buoyancy force effects on free convective chemically reacting fluids flow past a vertical plate in a Riga surface have been addressed numerically. Cattaneo-Christov theories, viscous dissipation, thermal radiation, thermophoresis and the Soret-Dufour mechanism were modelled in this paper. Also, thermal radiative heat flux was considered based on the Rosseland approximation because the fluid is optically thin. The flow equations were represented using partial differential equations (PDEs). These sets of PDEs were transformed into ordinary differential equations by utilizing suitable similarity variables. The transformed flow equations were numerically solved by employing the spectral collocation method. The outcomes show that enhancement in the velocity and temperature are observed due to an increase in Eckert number, thermal radiation and heat generation parameters. An increase in the relaxation heat and mass flux is noticed to have effects on the concentration and temperature gradient due to the presence of Soret-Dufour mechanisms. The present outcomes were compared with previously published works and are found to be in good agreement.

The purpose of this paper is to study the effect of heat transfer and flow of non-Newtonian power-law fluids towards a stretching sheet in the appearance of transverse magnetic field with slip boundary conditions. Suitable similarity transformations are used to change the non-linear partial differential equations to ordinary differential equations. For the numerical solution Maple software by applying built-in command dsolve with numeric is utilized. It is noticed from the obtained results that an increase in the magnetic parameter results in a decrease in the dimensionless velocity profile and in the stream function while the temperature profile increases for the Newtonian, dilatant, and pseudo-plastic fluids. Increasing the velocity slip parameter, a reducing behavior can be seen in the stream function and in the velocity profile while temperature profile is enhancing. Moreover, with increasing thermal slip, a decrease occurs in the dimensionless temperature. The variations in the velocity and temperature profiles under dimensionless parameters are significant for n = 0.8 (pseudo-plastic fluid) rather than for n = 1 (Newtonian fluid) and n = 1.02 (dilatant fluid).

“…Radiation can also introduce additional sources of heat, which can further impact the temperature distribution. These significant applications influenced many researchers to demonstrate the consequence of thermal radiation on MHD heat transfer under various geometries and conditions [1][2][3][4][5][6]. Mittal and Patel [7] assessed the Brownian motion and radiation impacts on magnetohydrodynamic Casson liquid flow in the sight of thermophoresis and heat generation.…”

The current investigation is purported on viscous heating dissipation and Hall consequences on mixed convection magneto‐hydrodynamic heat captivating fluid transmitting from an impulsively starting vertical porous plate with ramp surface temperature and concentration in the existence of chemical reaction and radiation. The dimensional flow dominating partial differential equations is translated into a non‐dimensional partial differential form by adopting appropriate variables and parameters. A finite element approach is driven to simplify the resulting dimensionless nonlinear linked partial differential equations with initial and boundary stipulates. The after‐effects of flow commanding parameters on the velocity components, temperature and concentration are broadly analysed graphically, whereas both primary and secondary shear stresses, heat and mass transferral rates close to the surface area of the plate are discussed in tables. The ultimate results of this research revealed that viscous heating dissipation, Hall current, and thermal and mass buoyancy responses intensify both velocity components, whereas the efficacy of magnetic fields and radiation degrade both velocity components. The temperature distribution devalues with increasing heat absorption and Prandtl number, but a contrary impulse was noted with viscous heating dissipation. Likewise, concentration distribution expands with time progress but decays with chemical reaction parameters. A comparative analysis among the current results and certain research studies in the literature manifests the results’ precision and correctness.
