The effect of wind speed on the performance of a split chimney

Sharifian, Ahmad (2012) The effect of wind speed on the performance of a split chimney. In: 2012 International Conference on Fluid Dynamics and Thermodynamics Technologies (FDTT 2012), 17-18 March 2012, Singapore.


In densely populated areas, smoke and toxic gases from chimneys are a matter of concern. The
concentration of the toxic gases should be lowered before reaching ground level. It has being conceived a
simple configuration including two half cylinders is potential to reduce the concentration of the toxic gases
within the chimney. The split chimney is modeled and its performance under a wide range of wind speeds is
evaluated. The results indicate that the split chimney does not have an ad verse affect on the discharge o f the
chimney and is able to reduce the concentration of the exhaust toxic gases at all wind speeds. The results also
show there is a side leakage as wind speed increases. Further studies are needed to improve the performance
of the split chimney.
