Abstract

The k-EPSILON turbulence model is first applied to a purely oscillatory flow. The predicted hydraulic characteristics such as the mean velocity profile, the phase difference and the eddy visxosity are found to be in close agreement with the measured results by Jonsson and Carlsen. Then, the calculation is carries out for an oscillatory flow accompanied with a unidirectional motion. The numerical results are compared with the theoretical ones which are obtained by the authors using the time invariant eddy viscosity models (Tanaka and Shuto). (A)
