Abstract

Turbulent air flow fields for an unflanged rectangular opening were calculated numerically using the standard k-ε turbulence model. The accuracy of the calculations was verified by experimental laser Doppler anemometer velocity measurements and by comparison with previous empirical centre-line velocity equations. The results show that the air flow into an unobstructed exhaust hood can be predicted quite accurately provided that the calculation grid and the calculation domain are properly chosen.
