Aerodynamics simulation of operating rooms

Résumé

The hospital is the place where we find simultaneously people whose health state is weakened, or vulnerable, and pathogenic micro-organisms able to worsen their health. Because these, the quality of the air in hospital must be in conformity with precise criteria in the buildings such everyday usage, and in particular in the buildings where some risk of specific pollution exist as in operating rooms. In this paper, we present a modelisation and three dimensional numerical study made in an operating room. Results could be used when new operating rooms must be conceived or others existing will be modified. It could be used to avoid risks and to allow all controls of any risks. The air flow modelling aim, by analysing the stream coherence, is to control the contamination in the operating area by bringing out the contamination dispatching within the operating room. It will allow to clearly understanding the complex coupled phenomena thanks to animation and to virtual 3D reality. The use of real data of the studied operating room (geometry, volume, extracted and blown air flow, temperature and hygrometry) will allow the determination of the drainage of air, the distribution of temperature, and the zones of poor air distribution. To be able to find the exact distribution zones of the contaminants, the chosen turbulent model has to be accurate with a good ability to predict the recirculation of the air. The obtained results show that only one of the four tested models can correctly define the recirculation of the air.
