abstract

In this work, we present a more realistic inlet boundary condition to simulate compressible and incompressible flows through micro and nano channels considering consistent momentum and heat transfer specifications there. At solid walls, a constant wall temperature with suitable jump is applied as the wall thermal boundary condition; however, two types of thermal inlet boundary conditions are investigated at the inlet. We firstly examine the classical inlet boundary condition, which specifies a uniform temperature distribution right at the real inlet. Alternatively, we apply the same boundary condition but at a fictitious place far upstream of the real channel inlet. To validate our results, the results obtained after employing the former boundary conditions are evaluated against other available numerical results and Lattice Boltzmann solutions. In this validation, the friction factor and Nusselt number are treated as the most important hydrodynamics and heat transfer factors to be appraised. Next, we present the results after applying the second type of inlet boundary conditions and compare them with those of applying the first type of boundary condition. This study suggests an innovation in micro/nano scale heat transfer treatment close to the channel inlets.
