Flow regime meaning
Web2.3.3.2.3 Random vibration. The most important difference between two-phase flow and single-phase flow is the random buffeting force in the two-phase intermittent flow regime. When not in the intermittent flow regime (e.g. in bubbly flow or mist flow), the vibration estimation is similar to that for single-phase flow except for the fluid density. WebSlip Flow Regime. In slip flow regime, the Knudsen layer takes a small portion of the channel height, which can be neglected by extrapolating the bulk gas flow towards the wall. ... The mean free path of gas molecules becomes smaller in nanopores because gas molecules collide with solid surfaces more frequently. Therefore, an effective mean ...
