The Reynolds number (Re) is an important dimensionless quantity in fluid mechanics used to help predict flow patterns in different fluid flow situations At low Reynolds numbers, flows tend to be dominated by laminar (sheet-like) flow, while at high Reynolds numbers turbulence results from differences in the fluid's speed and direction, which may sometimes intersect or even move counter to ,...

Would anyone be able to run an air flow simulation through the following geometry at 100 cc/min? I'm curious if any dead spots occur and if the geometry of the annular gap will produce laminar flow Dimensions are in inch Reynold's number analysis:...
Annular flow is a flow regime of two-phase gas-liquid flow (see gas-liquid flow)It is characterized by the presence of a liquid film flowing on the channel wall (in a round channel this film is annulus-shaped which gives the name to this type of flow) and with the gas flowing in the gas core...
The laminar flow equations for annular flow are approximate for Newtonian and power-law flow in annuli with low-clearance but reasonably accurate and much simpler than the exact solutions Note that for low clearance annuli, the slit flow model provides almost as accurate a result as the concentric annular model but can also be modified to ....

In Oil & Gas operations, it is frequently beneficial to flow fluids (gas, liquid, or both) vertically within an annular space Some surface facilities are starting to see a late-life benefit from converting large, under-utilized flow lines to dual-service by pulling a second pipe through the large line (and flowing produced water on the inner line and gas in the annulus)...
Laminar flow tends to dominate in the fast-moving center of the pipe while slower-moving turbulent flow dominates near the wall As the Reynolds number increases, the continuous turbulent-flow moves closer to the inlet and the intermittency in between increases, until the flow becomes fully turbulent at ,...
