“…does not obey the no-slip BCs and a slip occurs which has several engineering applications. Researchers [25][26][27][28][29] have discussed the impact of the first-order slip in various flow models. In spite of the many industrial and scientific applications of the second-order slip, the attention paid by researchers to this direction is very limited.…”

The current study explores the effects of second-order slip and activation energy (AE) on the magnetohydrodynamic and radiative fluid flow caused by a surface with exponential stretching. The binary chemical reaction with mixed convection is considered in this physical model to discover the heat transfer phenomenon. The governing system of equations leads to a set of nonlinear ordinary differential equations by using scaling analysis. The transformed system is calculated computationally by using the most powerful Shooting procedure with the support of MATLAB software. The characteristics of various flow parameters on the governing flow field are exhibited pictorially and deliberated. The results revealed that the coefficient of heat and mass transfer upsurge with growing values of the second-order slip parameter and skin friction coefficient has a reverse effect on the first-order slip parameter. The thermal measure of the fluid in the presence of suction and slip conditions is seen to be lesser than that with the nonslip and nonsuction conditions. The heat measure of the fluid augments with the rising buoyancy parameter. The influence of slips coupled with AE is significant in the fluid flow and heat transfer characteristics. The outputs of the current investigation are validated by comparing the Nusselt number with the available results and are found to closely agree as a limiting case.

The present investigation aims to analyze higher-order endothermic/exothermic chemical reactions with activation energy by considering thermophoresis and Brownian motion effects on MHD mixed convective flow across a vertical stretching surface. The influence of velocity slip, thermal slip, and concentration slip along with an inclined external magnetic field is also considered. The governing coupled non-linear partial differential equations are transformed into ordinary differential equations using similarity transformation. The resulting system of non-linear ODEs is solved by the Newton Raphson shooting technique using the RK-4 algorithm. The impact of various physical parameters discovered in the problem viz. endothermic/exothermic reaction variable, thermophoresis parameter, activation energy parameter, Brownian motion parameter, chemical reaction parameter have been analyzed on velocity profile, temperature profile, and concentration profile. The effects of these parameters on skin-friction coefficient, Nusselt number, and Sherwood number are displayed in tabular form as well as surface plots. The impact of various physical parameters that appeared in the entropy generation is shown using surface and contour plots. The numerical findings are in good agreement with the previously published results. It is observed that an increment in thermophoresis and Brownian motion parameters results in a declination of entropy profiles, whereas an increment in Bejan number profiles is observed. A small region near the surface exhibits an inclination in concentration profiles with an increase in the order of the chemical reaction. In contrast, the opposite effect is analyzed near the boundary layer. Also, the contour and surface plots are displayed to portray real-world applications in industrial and technical processes and the physical depiction of flow characteristics that arise in the current study.

Transport phenomena in hydromagnetic convective Carreau nanoliquid flow over an elongating cylinder: A statistical approach

et al. 2022

View full text Add to dashboard Cite

The current work presents the convective Carreau nanoliquid flow along an elongating cylinder in the presence of magnetic field and slip constraints. Thermal radiation, viscous dissipation, and Joule heating effects are also considered. The modeled partial differential equations (PDEs) are solved utilizing BVP5C (MATLAB built‐in function) and appropriate similarity transformations. It is noted that the velocity and temperature are inversely proportional and directly proportional to the Hartmann number, respectively. Consequences of various parameters on Sherwood number, Nusselt number, and drag coefficient are analyzed employing tables and graphs. It is noted that the Eckert number demotes heat transfer rate. Verification of the MATLAB code is guaranteed through a reduced study with previously published papers and a good agreement is observed. The simultaneous impact of parameters on the Sherwood number is analyzed using two‐dimensional plots. The influence of parameters on heat transfer rate and drag coefficient are further scrutinized using statistical techniques like correlation and regression.
