“…They found that as the rotation velocity increased, the lower wall heat transfer coefficient increased significantly, while the upper wall heat transfer coefficient increased slightly. Alsabery et al [27] numerically investigated the mechanisms of increasing convective heat transfer with two-phase water nanofluids in a three-dimensional horizontal wavy channel with high and low wavy surfaces with uniform temperature and adiabatic conditions, respectively. The results indicated that nanofluid flow in the undulating channel is higher, especially at higher volume fractions of nanoparticles and Reynolds numbers.…”

In this research, a numerical study of mixed convection of non-Newtonian fluid and magnetic field effect along a vertical wavy surface was investigated. A simple coordinate transformation to transform wavy surface to a flat surface is employed. A cubic spline collocation numerical method is employed to analyze transformed equations. The effect of various parameters such as Reynolds number, volume fraction 0-, Hartmann number, and amplitude of wave length was evaluated in improving the performance of a wavy microchannel. According to the presented results, the sinusoidal shape of the microchannel has a direct impact on heat transfer. By increasing the microchannel wave amplitude, the Nusselt number has risen. On the other hand, increasing the heat transfer in the higher wavelength ratio corrugated channel is seen as an effective method of increasing the heat transfer, especially at higher Reynolds numbers. The results showed that with increasing Hartmann numbers, the flow line near the wall becomes more regular and, according to the temperature gradient created, the Nusselt number growth.

“…The heat-transfer augmentation is affected by the offset ratio’s placement and the intensity of the wavy material. Alsabery et al 10 used a two-phase water base fluid in a 3D wavy permeable medium with top and bottom wavy edges induced with a constant temperature and isothermal circumstances to investigate the Brownian diffusion as convective energy transference enhancement methods. The findings revealed that the nanofluid flow in the wavy channel improved heat transmission, particularly when the Reynolds number and the nanoparticle volume fraction increased.…”

Two-dimensional mixed convection radiative nanofluid flow along with the non-Darcy permeable medium across a wavy inclined surface are observed in the present analysis. The transformation of the plane surface from the wavy irregular surface is executed via coordinate alteration. The fluid flow has been evaluated under the outcomes of heat source, thermal radiation, and chemical reaction rate. The nonlinear system of partial differential equations is simplified into a class of dimensionless set of ordinary differential equations (ODEs) through a similarity framework, where the obtained set of ODEs are further determined by employing the computational technique parametric continuation method (PCM) via MATLAB software. The comparative assessment of the current outcomes with the earlier existing literature studies confirmed that the present findings are quite reliable, and the PCM technique is satisfactory. The effect of appropriate dimensionless flow constraints is studied versus energy, mass, and velocity profiles and listed in the form of tables and figures. It is perceived that the inclination angle and wavy surface assist to improve the flow velocity by lowering the concentration and temperature. The velocity profile enhances with the variation of the inclination angle of the wavy surface, non-Darcian term, and wavy surface term. Furthermore, the rising value of Brownian motion and thermophoresis effect diminishes the heat-transfer rate.

Convective heat transfer of laminar forced convection in a wavy channel is studied in this paper. Numerical simulations of the 3D steady flow of Newtonian fluid and heat transfer characteristics are obtained by the finite element method. The effects of the Reynolds number ((10 ≤Re≤1000), number of oscillations (0 ≤N≤5) and amplitude of the wall (0.05 ≤A≤0.2) on the heat transfer have been analyzed. The results show that the average Nusselt number is elevated as the Reynolds number is raised, showing high intensity of heat transfer, as a result of the intensified effects of the inertial and zones of recirculation close to the hot wavy wall. The rate of heat transfer increases about 0.28% with the rise of the number of oscillations. In the transfer of heat along a wavy surface, the number of oscillations and the wave amplitude are important factors. With an increment in the number of oscillations, the maximal value of the average velocity is elevated, and its minimal value occurs when the channel walls are straight. The impact of the wall amplitude on the average Nusselt number and dimensionless temperature tends to be stronger compared to the impact of the number of oscillations. An increase of the wall amplitude improves the rate of heat transfer about 0.91% when the Reynolds number is equal 100. In addition, when the Reynolds number is equal 500, the rate of heat transfer grows about 1.1% with the rising of the wall amplitude.
