This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.Exhaust stacks emit pollutants that may be re-entrained into building outside air intakes, thus potentially creating indoor air pollution problems. These issues can be important for central plants, boiler exhausts, kitchen exhausts, and laboratories. Numerical methods, ranging from simple algebraic equations to computational fluid dynamics (CFD) have long been available as an alternative to wind tunnel modeling of exhaust stacks and dispersion of pollutants. This seminar explores recent trends and the current state of the art in numerical methods. CFD and simple equations are covered. Comparisons are made to some wind tunnel modeling as well.Updated Dispersion Model for the ASHRAE Applications and Lab Design HandbooksBrad Cochran, MemberProduct contains: recorded presentation, slides (PDF format), audio (mp3 format)CFD Approaches to Predicting Dilution from Exhaust Stacks in Urban AreasTed Stathopoulos, Ph.D., P.E., Member, Mauricio Chavez, Ali Bahloul, Ph.D.Product contains: recorded presentation, slides (PDF format), audio (mp3 format)Evaluation of Several Simple Numerical Methods Against Wind Tunnel ModelingMichael Ratcliff, Ph.D., P.E., MemberProduct contains: recorded presentation, slides (PDF format), audio (mp3 format)
