Pressure Drop in a Tube Bundle with the Countercharge Arrangement

Abstract

The paper considers working section of the hydraulic test bench simulating the most compact heat exchange surface with the spiral countercharge arrangement of tubes in the bundle. The bundle consists of 75 tubes arranged in a rectangular channel in the form of five rows in the transverse direction to the flow and fifteen rows in the longitudinal direction. The tubes have an inclination angle to the horizontal plane of 8°30'. Deviation of the local average velocity values from the average flow velocity over the section is not exceeding ± 10 % in the channel section in front of the entrance to the tube bundle. In the developed method for determination of the hydraulic resistance, static pressure measurement on the channel surface is the main experimentally obtained data. Pulse holes for the static pressure selection are positioned with a step equal to the tube longitudinal step in the bundle. It is experimentally determined that flow stabilization is achieved behind the seventh row of tubes. The paper determines hydraulic resistance of a tube bundle in the transverse flow in the range of Reynolds numbers from 1.3 • 10⁴ to 3.9 • 10⁴. Computed dependence is obtained for determining hydraulic resistance in the tube rows. The paper shows that alteration in the tubes arrangement in the parallel rows from parallel to the countercharge leads to a decrease in the tube bundle hydraulic resistance of 12--23 % (the lower value corresponds to the Reynolds number of 1.3 • 10⁴, the higher value --- 3.9 • 10⁴)
