Abstract

Entrance flow in a channel is investigated for high Reynolds numbers. In the limit Re → ∞ there exists a distinct structure of the flow field which can be taken into account by asymptotic methods. Contrary to the laminar flow situation, there is no need for an extra expansion in the immediate entrance region. The downstream expansion which results from a leading order momentum equation of slender channel type can be also used from the very beginning of the channel.
