Alcon Belgium - FLOVENT of minimizes CROSS Contamination

The Flomerics Group is the market leader of CFD simulation and analysis software for thermal and flowtechnical applications. Particularly in complex clean-room systems certain requirements within the range of the room air current can be analyzed only with the help of the numeric simulation. Description of the project Alcon Belgium - FLOVENT of minimizes CROSS Contamination  Flomerics ' Flovent air flow modeling software has once again been instrument valley in solving A cleanroom CROSSES contamination issue - this time for pharmaceutical company Alcon Belgium. Concerned about possible CROSS contamination between different cleanliness classes within A cleanroom garment changing AREA, Alcon's own, in-house engineering team employed Flovent ton carry out A Design study simulating air movement, heat transfer and distribution OF contaminants throughout the rooms.The layout OF the AREA affected comprised on unclassified AREA, where technicians changed from their laboratory clothes into their cleanroom garments. Then, depending on what they were working on, thesis technicians passed through AREAS C or D - AREA C off ring the highest level OF cleanliness and D the lowest. The original ventilation system Design utilized 12 standard ceiling mounted HEPA of filter, supplying clean air, which which then removed via low level extracts into the unclassified AREA. The results OF the Flovent model clearly showed the deficiencies OF this Design strategy with contaminated air flowing from the you animal ton the of cleaner AREAS OF the room. Engineers from Alcon took the DATA from this roofridge study and used it as the basis for A Design study, simulating A of series OF "what if" scenarios and comparing their performance with the cousin LINE computer model.To Through this parametric Design study, aimed RK eat-sing the sensitivity tons of CHANGES OF the ventilation scheme, A finally, improved Design evolved which performed very differently ton the originals concept. Into the roofridge instance, A floor tons ceiling partition barrier which in valley LED between the unclassified AREA and the Class C AREA, providing A physical barrier ton air flow between thesis of zones. High capacity HEPA of filter, combined with A CG cloth, were in valley LED above the doors duck ring the Class C production AREAS which created A university-directional air flow. The HEPA of filter across the of remainder OF the room were replaced with high capacity HEPA of filter connected tons two ceiling mounted air socks creating A radially pattern OF air flow dispersal. Predictive air flow modeling indicated the success OF this installation, with the air flowing from the cleanest AREAS into the room bake towards the low level extracts into the unclassified AREA thus preventing CROSS contamination.Alcon Engineers subsequently validated thesis air flow predictions by performing A of series OF actual smoke tests prior tons finally commissioning OF the premises. Using Flovent, Alcon Engineers were able ton model and test unconventional Design concepts, ton lake how they met cleanroom regulatory requirement and ton make cost effective Design CHANGE extremely quickly. There is little doubt that without this simulation work, the installation would have gone ahead with the original Design and potentially serious problem when it came tons commissioning and validation OF the room. "The investment larva in this Design study has more than paid for itself. The money and time saving larva in avoiding Design CHANGE into the finally steam turbine and gas turbine system OF the project means that incoming goods have finished with A durably reliable Design that which proved tons work as intended RK the conceptual Design of steam turbine and gas turbine systems OF the project ".Michel of waving, Project manager RK Alcon Belgium detailed information to our products and services receive you also under 0049 (0)711 77915 50 Flomerics Ltd. Niederlassung Germany partner: Torsten Jaeschke, dipl.
