A tracer gas was continuously released from a 1 m&lt;sup&gt;2&lt;/sup&gt; horizontal source 0.5 m above the floor. Path-integrated concentrations were measured along multiple short and long sampling paths in three horizontal planes. A steady state CFD analysis was used to model these experiments. The Reynolds Averaged Navier-Stokes (RANS) equations were solved for the flow and temperature field using the commercial CFD software, StarCD. CFD results were compared with the measured path-integrated concentrations. Accuracy of CFD predictions was found to improve with inclusion of thermal effects, and further by using a low-Re turbulence model.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">&lt;p&gt;3&lt;/p&gt;</style></custom1><section><style face="normal" font="default" size="100%">Chapter</style></section></record></records></xml>
