Abstract : Small-scale visualization experiments of a 4.3 m diameter and 78 m high stack with separate entrances for low temperature boiler gases and high temperature incinerator gases were performed to assess stack flow interactions. Salt water modelling with laser-induced dye fluorescence visualization was used to simulate the flows in specially designed water tunnel. Further analysis was achieved using a computational fluid dynamic (CFD) sciver. Experimental and numerical simulations for cases with and without induced swirl demonstrated demonstrated that for the latter case incinerator plume adherence to the stack wall occurs. This is due to entrainment by the wall jet formed by the as yet undeveloped boiler flow velocity profile (Author)
