Weigand, B. and Beer, Hans (1994):
On the Universality of the Velocity Profiles of a Turbulent Flow in an Axially Rotating Pipe.
In: Applied Scientific Research, 52 (2), pp. 115-132. ISSN 0003-6994,
[Article]
Abstract
If a fluid enters an axially rotating pipe, it receives a tangential component of velocity from the moving wall, and the flow pattern change according to the rotational speed. A flow relaminarization is set up by an increase in the rotational speed of the pipe. It will be shown that the tangential- and the axial velocity distribution adopt a quite universal shape in the case of fully developed flow for a fixed value of a new defined rotation parameter. By taking into account the universal character of the velocity profiles, a formula is derived for describing the velocity distribution in an axially rotating pipe. The resulting velocity profiles are compared with measurements of Reich 10 and generally good agreement is found.
