Abstract
Flow field of open channel flows with moderate adversed pressure gradients are measured by a Hot-film anemometer.Mean velocity profiles are expressed well by the log-wake law. In the fully developed flow condition, the velocity profiles are found to be self-similar in flow direction. Wake strength parameter II is expressed by Clauser's equilibrium parameter β.Reynolds stress distributions can be calculated from mean velocity profiles, by using of Rotta's equation. Turbulence intensities are expected by Bradshaw's experimental results.
