Original Abstract

The secondary flow is a key factor to the reinforced exhaust hood called Aaberg exhaust hood, as it makes use of the jet to limit spatially the room where the extraction takes place, and to generate additional suction effect due to the secondary jet flow. The jet has been investigated employing the LES turbulence model and compared with the results obtained with the use of another model, the standard k-e turbulence model in particular, and hot-wire anemometry. What was compared was: the velocity decay, profiles across the jet, the jet spreading rate and the generated velocity profile of the secondary flow. Some of the jet characteristics were also contrasted against the theoretical solutions.
