Air flow modeling helps overcome Cleanroom Moisture Condensation problem

The of challenges facing Merck and the FLOVENT Modeling services Group were ton: Simulate and evaluate the cleanroom Design, determine the reason for the condensation problem, and per float practical and economical modifications that would solve the problem with minimum adverse effect on cleanroom operation, which had tons of continue even as the modifications were being larva. The FLOVENT software, used tons conduct the analyses, employs mathematical modeling methods, based on Computational fluid Dynamics (CFD) techniques, ton accurately calculate environmental factors, looks for as air flow, heat transfer, and contaminationdistribution in three dimensionally spaces. Flomerics ' engineers built A precise computers model OF the Merck cleanroom. This model incorporated all pertinent geometrical and physical details, including placement OF the kettles and the ceiling mounted bank OF laminarly flow diffusers used tons supply the room's fresh air via low level exhausts.Working with the model, the engineers were able ton create A of series OF animated three dimensionally views that accurately simulated the actual air flow and moisture content conditions into the room. The FLOVENT simulation quickly illustrated that the moisture vapor which being carried aloft on the rising stream OF hot air from the opened vessels until the vapor condensed on the ceiling. The low level extracts had little influence into preventing the warmly, moist air reaching the ceiling. Investigation concluded installing additional high level that ford ago exhausts into the room could alleviate the condensation problem. Subsequent FLOVENT simulation were then used tons optimize the position OF the high level exhausts. It which found that if the exhausts were positioned too high then the water vapor would emergency sufficiently diluted before it reached the ceiling.Positioned too low, and the exhausts would emergency have enough influence ton prevent the warmly air rising past them and reaching the ceiling. Based on all thesis results and Flomerics ' recommendations, Merck larva the appropriate cleanroom modifications and economically solved the condensation problem while RK the same continuing normally cleanroom operation.
