Experimental Investigation of Pressure Distribution in Turbulent Flow Between Parallel and Inclined Disks

Abstract

Although the flow between parallel and inclined disks is a simple representation of many complex flow situations, this class of flow poses significant problems for experimental and numerical study. This paper presents experimental results of the pressure distribution for turbulent radial flow between parallel and inclined disks, considering different ratios between the diameters of the frontal disk and feeding orifice. The experimental results bolster the lack of data for both flow situations in the turbulent regime and demonstrate differences between them. The results presented have high accuracy and known uncertainty, making them useful for comparison to analytical and numerical results.
