Shallow Water Flow on a Rotating Circular Cylinder : 1st Report, The Case of a Still Cylinder

Abstract

Direct strip casting is attracting attention as a new method of production of steel plates. This paper describes the results of an investigation on how a liquid such as water flows on a circular cylinder. Depending on the nozzle height and water velocity at the nozzle exit, a roll wave, stationary-centrifugal-force wave, long wavelength wave, ripple and dimples appear, and a range of mirror-like surface flow between the exit Reynolds numbers of the roll wave and a stationary-centrifugal-force wave exists. The variations of water depth in the circumferencial direction are also measured.
