2%, and the phases are distributed in either a stratified flow or, as observed through the MFF sight glass, a mist flow with a very thin liquid annulus (Figure 4).
With respect to two-phase stratified flow system, the horizontal current induced by ISWs reverses the flow direction between upper and lower layers.
1979: Observations of stratified flow past three-dimensional barriers.
In a stratified flow, there is a smooth liquid-gas interface, without droplet entrainment in the gas phase, which travels above the liquid phase (Crowe, 2005).
Another mechanistic model was defined by [15], this model took into account the following flow patterns: dispersed bubble flow, stratified flow, annular mist flow, bubble flow, slug flow, and froth flow.
Pioneering work performed at the University of Houston provided mathematical relationships to predict the flow regime given gas and liquid velocities, including dispersed bubble flow, elongated bubble flow, slug flow and stratified flow to name a few.
2012), but especially for stratified flow in displacement ventilation.
01s-1 , sea depth H = 100m , stratified flow velocity V = 2m / s , C = x + Vt , horizontal scale of underwater streamlinedobstacle is about 50 m.
The result is a tendency to produce, in the tubes of an air-cooling evaporator, stratified flow that persists throughout the evaporator because there is not sufficient evaporation to get the vapor velocity high enough to break up the stratified flow.
The flow patterns were classified as follows: stratified flow, stratified flow with a layer of drops or three-layer flow, stratified/mixed flow, and dispersed flow (droplets of oil in water or vice versa).
