“…Also, the exergy efficiency is higher for novel system rather than rival system, and this is due to the presence of magnetic field in rival system. The external magnetic field induces a synergistic effect between the nanoparticles and the base fluid, and consequently, the exergy efficiency is increased (Anitha et al 2020). This in fact opens up the possibility of usage of porous media for heat transfer in industrial applications.…”

Heat transport finds use in several applications including heat exchangers, marine units, food processing units, oil and gas industries, petroleum industries and so on. By providing a large surface area and irregular motion in flow, made possible by porous media and enhances the thermal efficiency. The addition of a single type of nanosized particles in the base fluid gives rise to nanofluids. It tends to have higher thermal conductivity than the base fluid. However, currently hybrid nanofluids are introduced to overcome the disadvantages associated with nanofluids such as lower chemical stability, lower corrosion-resistant and so on. Hybrid nanofluids consist of dissimilar nanoparticles. Here, the heat transfer performance of nanofluids and hybrid nanofluids which flow through porous media is discussed. In addition, the role of the external magnetic field on the heat transfer performance of nanofluids with porous media is also explored. The relation between important parameters like Darcy number, porosity, Hartmann number, Reynolds number, Biot number and heat transfer performance of fluids with porous media is duly discussed. This chapter focuses on the role of porous media in enhancing heat transfer performance of nanofluids and hybrid nanofluids when flow occurs through different geometries.

The impact of heat-absorbing viscoelastic nanofluidic flow along with a convectively heated porous Riga plate with Cattaneo-Christov double flux was analytically investigated. The Buongiorno model nanofluid was implemented with the diversity of Brownian motion and thermophoresis. Making use of the transformations; the PDE systems are altered into an ODE system. We use the homotopy analysis method to solve these systems analytically. The reaction of the apposite parameters on fluid velocity, fluid temperature, nanoparticle volume fraction skin friction coefficients (SFC), local Nusselt number and local Sherwood number are shown with vividly explicit details. It is found that the fluid velocities reflect a declining nature for the development of viscoelastic and porosity parameters. The liquid heat becomes rich when escalating the radiation parameter. In addition, the nanoparticle volume fraction displays a declining nature towards the higher amount of thermophoresis parameter, whereas the inverse trend was obtained for the Brownian motion parameter. We also found that the fluid temperature is increased in viscoelastic nanofluid compared to the viscous nanofluid. When we change the fluid nature from heat absorption to heat generation, the liquid temperature also rises. In addition, the fluid heat is suppressed when we change the flow medium from a stationary plate to a Riga plate for heat absorption/generation cases.

“…Excellent achievements were done as the empirical linear and quadratic equations in account of Reynolds number for the optimum velocity and as well as for the pressure were deducted for the future predictions for such flows. With the use of hybrid nanofluid (a well-known coolant), a heat transfer procedure in a heat exchanger of industrial length containing the double tube with presence of magnetic field on it, a numerical study [15] was carried out. The heat transfer performance was checked with the volume fraction from 0.1% to 0.5% and the Reynolds numbers 800-2400 for the two hybrid nanofluids CNT-Al 2 O 3 and CNT-Fe 3 O 4 .…”

This paper provides numerical estimation of Newtonian fluid flow past through rectangular channel fixed with screen movable from 10° to 45° by increasing the Reynolds number from 1000 to 10,000. The two-dimensional incompressible Navier Stokes equations are worked out making use of the popular software COMSOL MultiPhysics version 5.4 which implements the Galerkin’s least square scheme to discretize the governing set of equations into algebraic form. In addition, the screen boundary condition with resistance coefficient (2.2) along with resistance coefficient 0.78 is implemented along with slip boundary conditions applied on the wall. We engaged to find and observe the relationship between the optimum velocity, drag force applied by the screen, and pressure occurred in the channel with increasing Reynolds number. Because of the linear relationship between the optimum velocities and the Reynolds number, applying the linear regression method, we will estimate the linear equation so that future prediction and judgment can be done. The validity of results is doing with the asymptomatic solution for stream-wise velocity at the outlet of the channel with screens available in the literature. A nondimensional quantity, i.e., ratio from local to global Reynolds number Re x / Re , is introduced which found stable and varies from -0.5 to 0.5 for the whole problem. Thus, we are in the position to express the general pattern of the velocity of the particles as well as the pressure on the line passing through the middle of the channel and depart some final conclusion at the end.
