Regime flow
WebThe flow regime (either laminar or turbulent) is determined by evaluating the Reynolds number of the flow (refer to figure 5). The Reynolds number, based on studies of Osborn Reynolds, is a dimensionless number comprised of … WebAnnular flow is a flow regime of two-phase gas-liquid flow. It is characterized by the presence of a liquid film flowing on the channel wall (forming an annular ring of liquid) while the gas flows as a continuous phase up in the center of the tube.The flow core can contain entrained liquid droplets. The velocity of the gas core is very large, and it is large enough …
