✦ Synopsis

A computational model predicting extent of smoke clouds from possible clean room "res has been developed using CO concentration as a marker for smoke concentration, which is believed to be more rigorous than the conventional approach relying on temperature pro"les. The computational results are compared with results of reduced scale clean room "re tests and are found to be favorable enough to be used in "eld applications. The numerical model is employed for simulations of clean room "res with a typical full-scale geometry. The impact of air circulation rate, "re size, and "re location on the extent of CO clouds, which could be converted to that of smoke clouds, has been analyzed. Sprinkler actuation and smoke detector locations for fast response with respect to di!erent operating conditions are also discussed. Overall, it has been illustrated that numerical simulations can be adopted as a very useful tool in investigating and customizing optimal set of design parameters at a new facility or estimating a scale of contamination at an existing facility against potential clean room "res.
