This study aims to evaluate the influence of manikin's turning motion on the airflow field in an operating room. A simplified three-dimensional model of the operating room was developed using computational fluid dynamics method. The RNG k-ε turbulence model was used to predict the airflow distribution. The manikin movement was introduced using a user-defined function code. Results show that the bent-forearm and upright turnings of the manikin could increase the airflow velocity in the surgical zone by 35% and 23%, respectively.

Keywords: computational fluid dynamics, airflow simulation, manikin movement model.
