ESTIMATION OF THE DOWNSTREAM FLOW OF VALVES

J. Prost, K. Käfer

Abstract

At the Institute for Waterpower and Pumps we use hot wire anemometry to investigate the downstream flow of valves in an air channel. The velocity distribution is determined point-by-point. Due to our experience and corresponding to the developments in data acquisition our measuring system has been adapted continually. Today the calibration of the probes, the velocity measurement and the data analysis is done computer aided. The paper reports on our system and the software developed by ourselves. The practical application of the system is demonstrated on the investigation of the downstream of a slide plate gate valve.
