Momentum and Kinetic Energy Coefficients in Symmetrical Rectangular Compound Cross Section Flumes


Abstract: In this study a series of laboratory experiments was conducted in nine models of symmetrical rectangular compound cross section having different dimensions for a wide range of discharges in order to investigate the effects of step height and main channel width on the kinetic energy coefficient, \alpha, and momentum correction coefficient, \beta. An overall kinetic energy correction coefficient and momentum correction coefficient were obtained from the data of all the models investigated. These numerical values can be used for any symmetrical rectangular compound cross section having similar geometry and similar range of Reynolds number.
