Aerosol Sampling [click here]
Radioactive particles bound to aerosols can be exposed to the environment by the stack releases of ventilation stations at CERN. Fractions of the outgoing air need to be sampled for monitoring measures, quantifying the radioactive releases. The present request concerns the estimation by means of CFD analysis of the sampling devices efficiency
ALICE ITS (Inner Tracking system) Upgrade [click here]
Air cooling is considered as a possible solution for the cooling of the upgrade of the Inner Tracking System (ITS) of ALICE, which is planned to be completed by the end 2018. Compared to implementations based on liquid or two-phase refrigerants, air-cooling would be an excellent solution in order to maximize the sensor accuracy as no material is introduced in the detector sensitive volume. The required cooling air velocity strongly depends on the local power density. Since the mechanical stresses due to this flow are expected to be the bottleneck of this cooling solution, as a general rule the minimization of the power density is needed in order to implement air-cooling. In the present work, a detailed study is carried out by means of Computational Fluid Dynamics (CFD) simulations.
