Computational Fluid Dynamics (CFD) allows the study of steady and transient behaviour of fluid systems in several engineering fields. Since 1993 CFD has been used at CERN, in particular in the TS-CV group, to solve several problems on thermo-fluid dynamics, especially related to LHC experiments in the development and design phases. These activities have been developed by a small team consisting mainly of fellows, associates and students. A number of analyses have been elaborated for the scientific community during these 11 years. Most of these studies are focused on thermal behaviour of different CERN systems, giving answers to the cooling efficiency of the equipments and suggesting new strategies for their design. CFD models can be built and analysed reducing the effort required for physical testing, saving time, money and allowing for additional investigation and design optimisation. The basis of computational fluid dynamics is the reduction of the continuum differential equations governing the dynamics of the fluid into a system of algebraic equations at a finite number of ?grid? points, and obtaining the solution to these equations there. The user can obtain a complete set of 2D and 3D images of the physical model showing a number of fluid dynamic variables (pressure, temperature, velocities, etc.). With a few mouse clicks one can change initial and boundary conditions of the model to obtain results on different configurations. Their comparison can allow the optimisation of the system. STAR-CD® is the software used for these kinds of CFD analysis. A presentation of the CFD team activities at CERN and STAR-CD® features will be open to all people interested.
