Predictions of turbulence behaviour using k-epsilon model in operating theatres

This work concerns turbulence levels in a practical operating theatre of a 1200 beds Egyptian modern teaching hospital. The turbulence characteristics were represented by a modified k - epsilon model. Then a series of experimental investigations were preformed in the operating room to investigate the flow and temperature patterns and to assess the validity of the numerical model to be used. The experimental results were compared to the predicted ones and found to be in a good agreement.High turbulence zones can be avoided by choosing a complex but suitable design of HVAC systems (selection of the supply air diffusers and exhaust ports are critical aspects to reach the sterile and comfortable environment required).
