Abstract

The study was carried to predict the pressure drop in the microtubes by applying a finite volume solver. The full Navier-Stoke s approach is examined for this kind of narrow tubes for the pressure drop evaluations. The complete form of the energy equation with the dissipation terms is also linked to the momentum equations. The computed pressure drop show good agreements with the experimental data. The effects of flow rate and channel geometry on the pressure drop of the system are also predicted.
