CFD Simulation of Air Pollution Distribution and Its Effect on Patients in Hospital Operating Rooms

Abstract

This paper uses the CFD technique to simulate the internal environment of a hospital operating room, including the surgical area that includes the patientand the surgical team. Moreover, this work provides mathematical simulation of many models to be placed in the air entry and air exit areas in the operating room to obtainthe optimal model of air distribution within the operating room. The results obtained matched well with experimental data from approved literature and standards. These results found that airflow and air velocity significantly affect the patient’s thermal comfort in the operating room.Besides, it is observed that some recirculation zone is formed, and this is a result of the heat generated by the surgical team and the accelerated air. This region is considered a source for the survival of the polluted air in the room. Keywords: CFD, Operating room, Numerical analysis.
