Ice Formation in a Pipe Containing Flows in the Transition and Turbulent Regimes

Abstract

The form of the ice growth that occurs in a pipe containing flows which are initially in the transition and turbulent regimes was investigated. The ice-band structure reported previously [1] for Reynolds numbers near transition was observed to be of steady state ice structure formed in a pipe for flows with Reynolds numbers over the entire range of the present investigation (up to ReD = 1.4 × 104). Difference were, however, observed in the nature of the transient approach to this steady state ice structure. The influence of the ice-band structure on pressure drop and on pipe freeze-off were also investigated.
