SOME CONSIDERATIONS ON HIGH VELOCITY FLOWS THROUGH CURVED OPEN CHANNELS

Abstract

In this paper, the simple method for the hydraulic analysis of the high velocity flows through curved open channels is shown with some numerical results which contain the longitudinal and transverse distributions of hydraulic variables. It is shown that the fundamental equations used here are equivalent to the previous studies by von Kármán and Lenau mathematically. The numerical results are divided into three groups qualitatively and compared with the analysis of von Kármán and Lenau. When R/B becomes lager, the numerical results will gradually approach to Lenau's solutions. It is also shown that the effects of the bottom shear stresses can be considered by extending the method used here.
