Computational Fluid Dynamics (CFD) applications
104Show room on map
Computational fluid dynamics (CFD) simulations help to understand fluid flow phenomena and their thermal impacts. These numerical methods have been largely used for several CERN projects during the last 25 years. Last decade parallel computing evolution has boosted the precision and the reliability of this method. The seminar will give an introduction to CFD method, a description of the CFD team at CERN and the projects it can treat, ranging from cooling and ventilation challenges to safety applications. The presentations will cover beam dump cooling of the SHIP experiment, helium temperature map in the CAST experiment and will showcase two on-going cases in more detail: the optimisation of ATLAS cavern air temperature map with simulation of possible ventilation system changes and an external aerodynamics study of the whole Meyrin site for pollution dispersion assessment.
