In the 1st. report, a theoretical and experimental analysis of flow patterns occuring around a single flat plate set on the lower wall of the flow passage, as the simplest type of turbulence promoter, was described. This 2nd report describes an experimental analysis in the case of a single flat plate set on the upper wall of the flow passage. The experimental results show that the relationships among the Reynolds number, the blockage ratio C and the coefficient of lossξ, are almost the same in both cases, but that the coefficient of mean pressure fluctuationζ, is larger when the flat plate is set on the lower than when set on the upper wall. The distributions of the peaks of the coefficients of the pressure fluctuation were also determined. These experimental results are very useful not only for the design of turbulence promoters but also for the design of heat conducters.
