“…Their results highlight that the effects of the viscous dissipation parameter vary the temperature distribution. Many researchers [136][137][138][139][140][141] introduced the viscous energy dissipation on the fully developed laminar flow in circular ducts. They showed the effect of viscous dissipation on the axial distribution of wall heat flux for power-law fluids in a thermally developed region.…”

“…The energy generation due to the viscous effect is more prominent in shear-thickening fluids than in shear-thinning fluids, with the same flow as illustrated in Figure 2a. Chen and Tso [138] investigated Nusselt number variation with Da for different Brinkman numbers for Newtonian and non-Newtonian fluids. They highlighted that for a Darcy factor Da < 0.3, the shear thickening fluid dominates over the shear-thinning fluid, while the reverse is true for Darcy factor Da > 0.3.…”

This paper aims to develop a review of the electrokinetic flow in microchannels. Thermal characteristics of electrokinetic phenomena in microchannels based on the Poisson–Boltzmann equation are presented rigorously by considering the Debye–Hückel approximation at a low zeta potential. Several researchers developed new mathematical models for high electrical potential with the electrical double layer (EDL). A literature survey was conducted to determine the velocity, temperature, Nusselt number, and volumetric flow rate by several analytical, numerical, and combinations along with different parameters. The momentum and energy equations govern these parameters with the influences of electric, magnetic, or both fields at various preconditions. The primary focus of this study is to summarize the literature rigorously on outcomes of electrokinetically driven flow in microchannels from the beginning to the present. The possible future scope of work highlights developing new mathematical analyses. This study also discusses the heat transport behavior of the electroosmotically driven flow in microchannels in view of no-slip, first-order slip, and second-order slip at the boundaries for the velocity distribution and no-jump, first-order thermal-slip, and second-order thermal-slip for the thermal response under maintaining a uniform wall-heat flux. Appropriate conditions are conferred elaborately to determine the velocity, temperature, and heat transport in the microchannel flow with the imposition of the pressure, electric, and magnetic forces. The effects of heat transfer on viscous dissipation, Joule heating, and thermal radiation envisage an advanced study for the fluid flow in microchannels. Finally, analytical steps highlighting different design aspects would help better understand the microchannel flow’s essential fundamentals in a single document. They enhance the knowledge of forthcoming developmental issues to promote the needed study area.

Chen and Tesso [15] studied the convection heat transfer of a laminar flow of a non-Newtonian fluid, power-law model, inside a duct in which porous material was inserted between parallel plates. They studied the effects of viscous dissipation for various values of Darcy number.…”

Porous materials are used in thermal devices such as heat exchangers to improvement the heat transfer. The heat transfer of a non-Newtonian fluid flow in an annular pipe with porous discs is numerically investigated in this paper. The flow regime in both porous medium and clear region are considered to be turbulent. The effects of power-law index of the non-Newtonian fluid and porous discs pitch variationson the heat transfer rate, friction coefficient are studied and compared to each other for two porous layer thicknesses. Finally, the thermal performance is defined which determines the optimum porous media and non-Newtonian fluid characteristics in the annular pipe.

“…In the study of convection heat transfer in porous media, the effect of viscous dissipation on the temperature distribution and convection heat transfer characteristics has been widely concerned. The researches of Nield et al [2,3], Haji-Sheikh et al [4,5], Hooman et al [6,7], Hung and Tso [8,9] and Chen and Tso [10,11] et al have showed that the viscous dissipation greatly affected the convection heat transfer in porous media. However, the studies above merely used the Newton fluid for research, while pay less attention to non-Newton fluid and the viscous dissipation in the energy equation.…”

Moreover, they compared the forced convection heat transfer with that of Newton fluid while neglected the influences of inertia effect.…”

Based on Darcy-Brinkman-Forchheimer flow model, this study analyzed the viscous dissipation effect on the forced, fully developed convection heat transfer in the flat channel filled with saturated porous medium of power-law fluid. Moreover, it derived the dimensionless calculation formulas for the axial velocity distribution and temperature distribution. Then the dimensionless formulas were numerically simulated by using classical Runge-Kutta method under constant heat flux boundary condition. The simulation results show that the dimensionless temperature distribution were affected greatly by Brinkman Number Br, Darcy number Da, Integrated Inertial Parameter F, and power-law index n.
