transitional flow

transitional flow

[tran′zish·ən·əl ′flō]
(fluid mechanics)
A flow in which the viscous and Reynolds stresses are of approximately equal magnitude; it is transitional between laminar flow and turbulent flow.

Compared with the models in the reservoir without bottom-water drive, early flow regimes still can be recognized easily (i.e., wellbore-storage flow, transitional flow, and steady flow regime), while the late pressure behaviors may be covered due to the effect of bottom water.
Other key improvements include modeling of transitional flow regime for siphons and the taking into account of local time changes when calculating wastewater or trade waste profiles; the ability to export ground model grids to Esri ASCII raster format; more flexibility in editing scenario notes, layer themes and custom graphs and importing RTK hydrographs from SWMM5; and new results fields for flow direction.
The transitional flow regime is characterized by mixing laminar and turbulent flows.
The authors have organized the main body of their text in eight chapters devoted to nonlinear problems of transitional flow, fluid mechanics and nonlinear dynamic modeling, simulation and modeling of two phases flow, and a wide variety of other related subjects.
Squares correspond to transitional flow. Diamonds correspond to closed flow.

Actually this flow pattern is a transitional flow pattern from stratified flow to dispersed flow.
The Reynolds number at the tube inlet is about 2900, which is in the transitional flow region.
Aspect ratio effects on turbulent and transitional flow in rectangular microchannels as measured with micropiv.
Very good match is seen for the laminar flow data with slight underprediction for the points close to transitional flow. In the graph, predictions in the transition region are also shown and the comparison with the data shows that probably the transition occurs earlier than is predicted by current methodology.
Transitional flow is measured in real time for superior accuracy and less product waste, resulting in more money to the bottom line.
Thus, the airflow in a room with a weak jet could contain the combination of turbulent, laminar, and transitional flow. Thermal buoyancy from occupants could form unstable plumes.
