Flow regime meaning
WebAug 31, 2024 · A low flow is typically a seasonal phenomenon (e.g., the "dry season") and is an important component of the flow regime in any river or stream. By contrast, a drought is an event that results from an extended period of below average precipitation. While droughts include low flows, a continuous seasonal low-flow event is not necessarily a … WebSlug Flow is a typical two-phase flow where a wave is picked up periodically by the rapidly moving gas to form a frothy slug, which passes along the pipe at a greater velocity than the average liquid velocity. In this type of flow, slugs can cause severe and, in some cases, dangerous vibrations in piping systems because of the impact of the ...
