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 inches.
Reynold's number analysis:
Hydraulic Diameter* = 0.003 in = 7.62E-5 m Absolute Viscosity of Air at 20.2C = 1.983E-5 N-s/m^2 Density of Air at 20C = 1.293 kg/m^3 Mean Velocity = => A_cs = 0.004089 cm^2 => Q = 100 cc/min => V = 24455.9 cm/min = 4.076 m/s
Re = (rhoVD)/nu = (1.293 kg/m^3 * 4.076 m/s * 7.62E-5 m) / 1.983E-5 N-s/m^2 Re = 20.25
