Abstract

There is a demand to lower the concentration of toxic gases and smoke in the vicinity of the chimneys at low wind speed. This article deals with the advantages of using a novel and low-cost configuration which has already successfully been used to generate fire-whirls in the laboratory. The computational results show that the configuration named split chimney is able to generate a swirling flow when a hot air flow is used instead of a fire. In addition, the results show that the split chimney is able to lower the concentration of harmful gases at the outlet of the chimney without significant adverse effect on the plume rise.
