Abstract
CFD (Computational Fluid Dynamics) modelling of
particle transport has been applied for the control of airborne particles
in the operating zone above the surgery table in an operating room. Based
on the numerical results, it has been found that the particle source
location, air (supply) inlet design, operating table location, and lamp
design are among the critical parameters
responsible for the particle distribution within the operating room.
Key words: operating room, air flow, particle distribution, particle concentration, numerical modelling
