Title: CFD-based design of the ventilation system for the PHENIX detector

Conference ·
OSTI ID:392711

The three-dimensional flow and thermal fields surrounding the large PHENIX sub-atomic particle detector enclosed in the Major Facility Hall are simulated numerically in this study using the CFX finite volume, commercial, computer code. The predicted fields result from the interaction of an imposed downward ventilation system cooling flow and a buoyancy-driven thermal plume rising from the warm detector. An understanding of the thermal irregularities on the surface of the detector and in the flow surrounding is needed to assess the potential for adverse thermal expansion effects in detector subsystems, and to prevent ingestion of electronics cooling air from hot spots. With a computational model of the thermal fields on and surrounding the detector, HVAC engineers can evaluate and improve the ventilation system design prior to the start of construction. This paper summarizes modeling and results obtained for a conceptual MFH ventilation scheme.
