“…Rashidi et al [14] studied theoretically the boundary layers of the generalized third-grade viscoelastic power-law fluids. Khalili et al [15] adopted the power-law fluid to configure nanofluids and presented the effects of both the Brownian motion and the thermophoresis on the nanofluid boundary layer over a stretching plate. Rashidi et al [16] discussed the natural convection of incompressible non-Newtonian third-grade fluids flowing through two parallel surfaces.…”

In this article, we explore the heat transfer of non-Newtonian liquid food in the heating process in a channel connecting a tank. To achieve a rapid heat diffusion, several cylindrical agitators are inserted into the tank. We pay special attention to a Chinese traditional food, i.e. the black sesame paste, which is predicted by the powerlaw model. The fluid flow and heat transfer are investigated numerically, under the impacts of the angular velocity of cylinder, the stirrer size and the rotational direction. Three different settings are investigated: the two-stirrer, the three-stirrer, and the 2 × 2 stirrer settings. Several applicable strategies could be applied to improve the heat transfer in food engineering practices, including changing the size, the rotational velocity, the direction, and the number of stirrers in the heat exchanger.

In the present study, our aim is to present a novel model for the flow of hybrid nanofluids in oblique channels. Copper and aluminum oxide have been used to obtain a novel hybrid nanofluid. The equations that govern the flow of hybrid nanofluids have been transformed to a set of nonlinear equations with the implementation of self-similar variables. The resulting system is treated numerically by using coupled shooting and Runge–Kutta (R-K) scheme. The behavior of velocity and temperature is examined by altering the flow parameters. The cases for narrowing (convergent) and opening (divergent) channels are discussed, and the influence of various parameters on Nusselt number is also presented. To indicate the reliability of the study, a comparison is made that confirms the accuracy of the study presented.

“…Rashad [31,32] investigated the impact of thermal MHD slip flow of a nanofluid over a nonisothermal wedge and an inclined stretching surface, respectively. Rashidi and co-authors [33][34][35][36][37] presented a comprehensive review of last theoretical and experimental studies on thermal conductivity of nanofluids. Li et al [38] studied the effects of the Lorentz force and the induced anisotropic thermal conductivity due to a magnetic field on the flow and the heat transfer of a ferrofluid.…”

In the current framework, a model is constituted to explore the impacts of high suction and partial slip on Fe3O4–water nanoliquid flow over a porous moveable surface in a parallel free stream. The mechanisms of heat transfer are also modeled in the existence of Newtonian heating effect. The obtaining PDEs are transformed into a non-linear ODE system employing appropriate boundary conditions to diverse physical parameters. The governing ODE system is solved using a singular perturbation technique that results in an analytical asymptotic solution as a function of the physical parameters. The obtained solution allows us to carry out an analytical parametric study to investigate the impact of the physical parameters on the nonlinear attitude of the system. The precision of the proposed method is verified by comparisons between the numerical and analytical results. The results confirm that the proposed technique yields a good approximation to the solution as well as the solution calculation has no CPU time-consuming or round off error. Numerical solutions are computed and clarified in graphs for the model embedded parameters. Moreover, profiles of the skin friction coefficient and the heat transfer rate are also portrayed and deliberated. The data manifests that both solid volume fraction and slip impact significantly alter the flow profiles. Moreover, an upward trend in temperature is anticipated for enhancing Newtonian heating strength. Additionally, it was found that both the nanofluid velocity and temperature distributions are decelerated when the solid volume fraction and suction parameters increase. Furthermore, a rise in slip parameter causes an increment in velocity profiles, and a rise in Biot number causes an increment in the temperature profiles.
