Kind of new in CFD, so just wondering in doing a report what plots and where to place them in the model and what are the only important section to show in CFD distribution plots
Hi Marck. Yes, it does. If the width of the hot aisle is not large enough, and the racks are densely populated, the pressure in the center of the hot aisle will rise considerably, causing leakage around the rack rails and back through the IT cabinet into the cold aisle. This is due to the change in momentum of the hot air as it turns 90 degrees to go up and out through the hot aisle exhaust plenum.
@@aircleanersinc8279 okay thanks, Also what causes low pressure in some area of the data hall and inside the containment just behind the server discharge?

does hot aisle size affects pressure?
