“…Swain et al [18] used this model to report the consequence of allowing the Williamson nanofluid through porous medium consideration of irregular heat source/sink. Kho et al [19] looked into transmission of heat and mass when Williamson nanofluid is passed over the stretched surface. Chu et al [20] gave away the importance of activation energy, bio-convection and third grade fluid flowing over a stretched surface.…”

The current examination delves into the Casson nanofluid flow in the vertical microchannel. The model employed in this investigation is Buongiorno model which emphasizes the light on Brownian motion and thermophoresis effects occurring during the fluid flow. The microchannel walls are constructed in such a way so that they facilitate the suction and injection of the fluid simultaneously. Porous media is incorporated using Darcy-Forchheimer model. Involving these effects governing equations are modeled which is solved using Runge-Kutta Fehlberg 4 th -5 th order method. Entropy generation and Bejan number are also obtained for the concerned flow to record irreversibilities in the microchannel. The findings of this examination depict that rise in Casson parameter augments the flow velocity but causes depletion in Bejan number. On packing the microchannel with high porosity, the velocity magnifies. Both Brownian motion and thermophoresis parameter magnifies the temperature.

“…The result they found is skin friction coefficient lessen with an inflated velocity slip framework. Mass and heat relocation analysis of Williamson nanofluid with slip parameter is considered by Kho et al 30 They found that the width of boundary layer diminishes as the slip parameter increase. Velocity slip aspect reverses the wall velocity gradient is discovered by Seth et al 31 they consider radiative fluid flow through stretching sheet together with joule dissipation effect.…”

During this exploration, Casson nanofluid is taken over a sheet that is curved and stretching in nature and its flow equations are analyzed. Radiation and slip provisions are also taken into consideration. A magnetic field of uniform rate is provided. Convective heat and mass transference extract dominant conclusions from the system. The Brownian migration together with thermophoresis is also included in the flow structure. Moreover, the chemical reaction of higher-order within the nanoingredients also generates interest. Guiding equations furnished by the selected model are resettled to ordinary differential equations of nonlinear type by significant similarity transformation. We have worked on MAPLE-19 software to work out this with a suitable accuracy rate.Upshots are shown with diagrams and tables. Corresponding physical consignment such as Nusselt number has been analyzed. Determination of skin friction and moreover Sherwood's number is also in the area of interest. Magnificent advancement in heat sifting is dealt with by magnetic and Brownian motion specification. The graphs prescribed the upshots of thermophoresis and slip parameters. Outcomes convey that temperature together with concentration are reduced for stretching parameters but velocity lines are enhanced. Heat transport goes up for magnetic and

Numerical Chebyshev finite difference examination of Lorentz force effect on a dissipative flow with variable thermal conductivity and magnetic heating: Entropy generation minimization

This work presents the computational analysis of entropy generation minimization in a dissipative flow of viscous fluid. The flow is produced by a non-linearly elastic surface under the influence of the variable magnetic field. The nonisothermal boundary condition is chosen such that all the embedding flow control parameters are free from the space variables. It is supposed that the working fluid's thermal conductivity is temperature-dependent. The heating term corresponding to the magnetic dissipation effect is also added to the energy equation. The governing energy and momentum equations are simplified by similarity transformations and numerically solved using Chebyshev Finite Difference Scheme (ChFDS). Volumetric entropy generation in dimensionless form is also obtained via similarity transformations. The obtained solutions are also utilized for calculating entropy and Bejan numbers. It has been noticed that the production of entropy is highest at the surface of the elastic boundary. The temperature and entropy have increasing relation with the Eckert number and magnetic parameter. Further, an inverse relation is observed between the entropy generation and temperature difference parameter. The consequences of relevant parameters on the velocity, temperature, entropy and Bejan number are visually described and discussed.
