N2 - The dependence between the shear stress and integral flow parameters such as fluid flow rate still remains unclear for different microchannel geometries. We present results of the numerical simulation of the 3D fluid flow in a microchannel with a rectangular cross section. Basing on the experimental measurements of the pressure drop the fluid flow and the shear stress are analyzed in detail giving the correlations for the friction factor. The results show that the shear stress for a numerical calculation can be estimated using friction factor from the well-known formula with a slight deviation due to wall and corner effects which can be important with the reduction of microchannel size.
