abstract
The mechanism for maintaining turbulent secondary flows in ducts and open channels of non-circular cross section is examined from a theoretical standpoint. It is proven mathematically that no turbulence model based on isotropic eddy viscosity concept predicts secondary motion. Furthermore, necessary conditions for a turbulence model which includes driving mechanism of the secondary flow are briefly discussed.
