説明

The fully-developed flow of an incompressible fluid through curved pipes with elliptic cross sections is investigated analytically and experimentally. The velocity profile of the primary flow and the flow pattern of the secondary flow are determined by numerical analysis. Also, studies are conducted on the effect of the shape of the cross section upon the friction coefficient which is necessary for the industrial engineering. The experimental results on the pressure drop are compared with the analytical results. An approximate expression for the friction coefficient, taking into account the effect of the aspect ratio and the helical tube pitch, is derived on the basis of the analytical and experimental results.
