Applicability limits comparison of k-w turbulence model and Reynolds stresses transfer model in the problem of intensification of mass transfer by controlled rotary-divergent flow
This problem can arise in mechanics, chemistry, and catalysis in the mass transfer intensification. The mass transfer characteristics were measured in a controlled rotary-divergent flow. The laser Doppler anemometer was used for turbulent mass transfer diagnostics. The experimental investigation was...

| description | This problem can arise in mechanics, chemistry, and catalysis in the mass transfer intensification. The mass transfer characteristics were measured in a controlled rotary-divergent flow. The laser Doppler anemometer was used for turbulent mass transfer diagnostics. The experimental investigation was the one used to verify the numerical calculations. The numerical simulation has shown the presence of a near-wall jet after a rotary device and the reverse flow zones formation. The model of Reynolds stress transfer more adequately describes the flow in range of flow rates from 50 to 250 Nm3/h than k-w turbulence model. |
