Operating rooms: Numerical modeling of heat and mass transport phenomena

The operating room is the environment inside of hospitals that requires the greatest deal of attention in the choice of the devices for air supply, diffusion and recovery. The design of Heating Ventilation and Air Conditioning (HVAC) systems dedicated to these environments plays a crucial role, in order to drastically reduce the risk of infections for patients, in addition to the maintenance of adequate thermo-hygrometric comfort conditions for the medical team. The proper design of such systems must take into account air distribution and pollutants transport within the operating room. In the present work, the authors numerically simulate heat and fluid flow inside the room, and CO2 distribution

CFD modelling of an operating theater

The operating theater is the environment inside the hospital that requires the greatest deal of attention in the choice of the devices for air supply, diffusion and recovery. The design of Heating, Ventilation and Air Conditioning (HVAC) systems dedicated to these environment plays a crucial role to drastically reduce the risk of infection for patients, in addition to the maintenance of adequate thermo-hygrometric comfort conditions for the medical team. As a result, a lower risk of sepsis has been reported thanks to a cleaner air injection in operating theaters. In this work, the authors have reproduced numerically the air distribution inside an operating theater, where a swirl diffuser system is present. The numerical results have been validated against the experimental data obtained during field campaign. The objective of the present work is to develop an effective and robust numerical model able to reproduce the fluid dynamics phenomena inside operating theaters
