Abstract
The purpose of this paper is to study in detail the flow over an inclined fence in a turbulent boundary layer, as basic research which issues from promoting heat transfer and the decrease of the pressure drop. The fence height h set in a turbulent boundary layer is 1 mm (u_rh/ν ≑ 25,u_r : friction velocity, ν : kinematic viscosity) and setting angle of a fence is 20° in the free stream direction. The velocity profiles in the downstream of the fence were measured by I-shaped hot-wire probe and we investigated turbulence characteristics. Consequently, we clarified the turbulence intensity profiles and probability density functon profiles, and the skewness, flatness.
