On Circulating Water Channel Newly Built at University of Osaka Prefecture

Abstract

The authors present here the general remarks and the principal performances of a circulating water channel constructed lately at the Department of Naval Architecture, College of Engineering, University of Osaka Prefecture. The circulating water channel is of a horizontal type and the dimensions of the working section are 6.55 m in length, 1.5 m in breadth and 1.0 m in drart. Discussions are made about the results of the measurements of velocity distributions, velocity fluctuations and the free surface undulations in the working section as well as the results of resistance tests of a ship model and a flat plate at zero incidence.
