Abstract :

One of the primary needs of industrial applications is to enhance the energy transfer rate from one medium to another. However, the use of conventional fluids sometimes limits efficient energy transfer. Thus, the dynamic process of improving heat transfer is by using nanofluids. Choi (1995) introduced a mixture of nanoscale particles and conventional fluids to enhance heat transfer efficiency to produce nanofluids. Since then, the new topic of nanofluids has received significant attention from researchers due to its importance in the science, engineering, nanotechnology, and biophysics fields. On the other hand, convective heat transfer in a fluid-saturated porous medium plays a crucial role in geophysical (underground water, carbon dioxide sequestration, crude oil extraction, etc.) and industrial applications (refrigerators, heat sinks, thermal insulators, etc.). Heat transfer in a porous medium substantially depends on the thermal state of the porous matrix and the working fluid. When a fluid flows through a porous medium, it may be in locally thermal equilibrium (LTE) form to the porous matrix or may not. There are many situations where a thermally non-equilibrium (LTNE) state needs consideration. Here, we examine the convective heat transfer in nanofluids considering LTE and LTNE states between fluid and permeable matrix. We successfully identified the role of distinct factors in constructing a physical model dealing with flow dynamics and heat transfer. Key words: Nanofluids, Heat and Mass Transfer, Transport in Porous Media, Magnetohydeodynamics, Non-Newtonian Fluids
