ABSTRACT
Three dimensional heat transfer characteristics and pressure drop of water flow in a set of rectangular micro tubes were numerically investigated. A FV solver was employed to predict the temperature field for the conjugate heat transfer problem in both the solid and liquid regions in the micro channels. The full Navier-Stoke’s approach was examined for this kind of narrow tubes for the pressure drop evaluations. The complete form of the energy equation with the dissipation terms was also linked to the momentum equations. The computed thermal characteristics and pressure drop showed good agreements with the experimental data. The effects of flow rate and channel geometry on the heat transfer capability and pressure drop of the system were also predicted.
