“…They found that the nanoparticles significantly improved the heat transfer process. Other recent studies related to the non-Newtonian nanofluid flow could be found in Kodi et al, [3][4][5][6], Vaddemani et al, [7], Kommaddi et al, [8] and Suresh Kumar et al, [9]. Rafique et al, [10] reported the increment of heat transfer rate by 1.135% for single walled carbon nanotubes (SWCNTs) and 1.275% for multi walled carbon nanotubes (MWCNTs) with the application of suction parameter.…”

This work features the numerical computation and statistical analysis (response surface and sensitivity) for the flow and thermal progress of an axisymmetric copper-alumina/water hybrid nanofluid subjected to a permeable shrinking disk. The simultaneous factors of magnetic field (MHD), heat generation and suction parameter in the heat transfer development and flow characteristic are observed. The flow and energy equations are mathematically developed based on the boundary layer assumptions. These equations are then simplified with the aids of the similarity variables. The numerical results are then generated by the bvp4c solver in the Matlab software. The dual solutions are possible and exist up to a separation value upon the inclusion of suction effect. The increment of heat generation parameter from 0% to 1% reduces the heat transfer rate for all values of the stretching/shrinking parameter. For the response surface analysis, the responses (skin friction coefficient and heat transfer rate) are analyzed for three factors (magnetic, suction, heat generation) and three magnitudes (low, medium, high). Based on this analysis, the magnetic and suction parameters provide a significant effect on the skin friction with p-values < 0.05. Meanwhile, for the heat transfer coefficient, all factors give significant impact with zero p-values. Meanwhile, the sensitivity analysis reveals that the suction parameter has higher sensitivity to the heat transfer as compared to the magnetic and heat generation parameter. Even though these parameters being less sensitive, their influence on heat transfer remains statistically significant.

“…Ganji et al [23] examined the entropy production on the Hagen-Poiseuille flow of viscous fluid within a circular pipe due to the variable viscosity and heat transfer. Numerous studies have been conducted on non-Newtonian fluids with heat and mass transfer under different effects and flows, in a porous medium and a magnetic field [24][25][26][27]. These studies have examined the impacts of pertinent parameters on concentration, velocity, volumetric flux and temperature fields.…”

This study explores the influence of an inclined magnetic field and variable viscosity on the entropy generation in steady flow of a couple stress fluid in an inclined channel. The walls of the channel are stationary and non-isothermal. The fluid flow is driven due to pressure gradient and gravitational force. Reynold’s model for temperature-dependent viscosity was used. The dimensionless, non-linear coupled equations of momentum and energy was solved, and we obtained an analytical solution for the velocity and temperature fields. The entropy generation and Bejan number were evaluated. The variation of pertinent parameters on flow quantities was discussed graphically. The rate of volume flow, skin friction coefficient, and Nusselt number at the surfaces of the channel were calculated and their variations were discussed through surface graphs. From the results, it is noticed that the entropy generation rate can be minimized by increasing the magnetic field and the temperature difference parameters. The findings of the current study in some special cases are in precise agreement with the previous investigation.

The purpose of present study is to analyse the influence of Hall current and thermal radiation MHD electrically conducting nanofluid flow past a continuously stretching surface with heat absorption/generation in the presence of Brownian motion and Thermophoresis has been explored. Transverse magnetic field with the assumption of small Reynolds number is implemented vertically. Appropriate similarity transformations are utilized to transform the governing partial differential equations into the non-linear ordinary differential equations. Numerical solutions for the dimensionless velocity, temperature and nanoparticle concentration are computed with the help of the shooting method. The impact of each of the Hall current parameter, thermal radiation parameter, Heat source/sink parameter, Brownian motion parameter, thermophoresis parameter and magnetic parameter on velocity, concentration and temperature, is discussed through graphs. The skin friction coefficient, the local Nusselt number and the Sherwood number are calculated numerically to look into the inside behaviour of the emerging parameters. It is witnessed that the flow velocity is a diminishing function of the linear and non-linear thermal radiation parameter. Moreover, mounting values of Brownian motion parameter reduce the nanoparticle concentration profile.
