The relatively new approach of wind modeling to determine the effectiveness of an exhaust stack configuration offers energy engineers a useful tool to optimize effluent dispersion from a laboratory-type facility. The technique is generally recognized as accurate for modeling dispersion of exhaust gases; however, wind modeling is a complex science, and the modeling tools that have been developed from wind-tunnel simulations are beyond the scope of this design guide. It is strongly recommended that this modeling be completed because of the energy savings that can be realized from exit velocity reductions. [Peterson, 2002]
