“…Earlier, many researchers calculated the viscous dissipation implication for the flow past the stretching surface. [19][20][21][22][23] Reddy 24 debated the viscous dissipation effect on MHD convection flow over a stretched upright plane plate and identified the fluid velocity and temperature region increment as the viscous dissipation parameter improves. Jamalabadi and Park 25 examined the influences of thermal radiation, Joule heating, and viscous dissipation on MHD forced convection flow and portrayed the notable influence of the viscous dissipation effect.…”

The present analysis addresses linear and nonlinear radiation effects in hydrodynamic viscous Maxwell fluid flow on a unidirectional stretching surface through viscous dissipation. The relaxation effect is considered in the mathematical model, which elucidates mass transport mechanisms under binary chemical reaction and activation energy. Mathematical modeling contains nonlinear partial differential equations using boundary conditions. Appropriate transformations convert the partial differential equations into ordinary differential equations. Numerical solutions for regular differential equations are brought by Runge-Kutta-Fehlberg numerical quadrature and a shooting method with a tolerance level of 10 −9 . The influence of physical variables, such as Deborah relaxation number, rotation parameter, Biot number, activation energy parameter, reaction rate parameter, Eckert number, and Prandtl number are investigated.Increasing the Biot number improves the temperature region in the boundary layer. With high rotation, the increasing Deborah number enhances the fluid temperature substantially throughout the boundary layer.

“…Most notably, it smooths the surface of nucleate sites, resulting in significant thermophysical coefficient degradation. Khan and Pop [31], Yirga and Shankar [32], Pourmehran et al [33], Jahan et al [34], Hafidz et al [35], and Gangadhar et al [36] are some of the scholars and scientists who have reported the MHD movement and analysis of heat in a steady porous medium under the influence of viscous dissipation and chemical reaction. The similarity equations were solved by implementing the Keller-box scheme.…”

The process of thin films is commonly utilized to improve the surface characteristics of materials. A thin film helps to improve the absorption, depreciation, flexibility, lighting, transport, and electromagnetic efficiency of a bulk material medium. Thin film treatment can be especially helpful in nanotechnology. As a result, the current study investigates the computational process of heat relocation analysis in a thin-film MHD flow embedded in hybrid nanoparticles, which combines the spherical copper and alumina dispersed in ethylene glycol as the conventional heat transfer Newtonian fluid model over a stretching sheet. Important elements such as thermophoresis and Brownian movement are used to explain the characteristics of heat and mass transfer analysis. Nonlinear higher differential equations (ODEs) were attained by transforming partial differential equations (PDEs) into governing equations when implementing the similarity transformation technique. The resulting nonlinear ODEs have been utilized by using the homotopy analysis method (MHD). The natures of the thin-film flow and heat transfer through the various values of the pertinent parameters: unsteadiness, nanoparticle volume fraction, thin-film thickness, magnetic interaction and intensity suction/injection are deliberated. The approximate consequences for flow rate and temperature distributions and physical quantities in terms of local skin friction and Nusselt number were obtained and analysed via graphs and tables. As a consequence, the suction has a more prodigious effect on the hybrid nanofluid than on the injection fluid for all the investigated parameters. It is worth acknowledging that the existence of the nanoparticles and MHD in the viscous hybrid nanofluid tends to enhance the temperature profile but decay the particle movement in the thin-film flow. It is perceived that the velocity and temperature fields decline with increasing unsteadiness, thin-film thickness and suction/injection parameters.

This investigation is performed for exploring the steady boundary layer flow of mixed convective boundary layer flow of non-Newtonian nanofluid over a stretchable sheet with convection heating. Eyring-Powell fluid is considered as working fluid. The impact of heat absorption/generation, Brownian motion and thermophoresis are taken into consideration. Nonlinear ordinary differential equations are derived from governing equations by utilizing the similarity transformations. To get solution SQL method is used. Accuracy of the proposed technique is checked by comparing with numerical approximations of proposed technique and with results available in literature. The study of parametric approach produces the influence of flow, heat and mass transfer processes. The outcomes of proposed study revealed that parameter of Eyring-Powell fluid ԑ reduces the velocity of the flow and thickness of the momentum buoyancy layer for both assisting and opposing flow conditions while it enhances the temperature and concentration profiles for both flow conditions.
