  2. Abstract:
  3. Surgical site infection (SSI) is one of the important infectious problems in hospitals. It is well known that appropriate ventilation strategy is most effective way to control bacteria-carrying airborne particles responsible for SSI. With considerable improvement in the computational capacity of computers, computational fluid dynamics (CFD) technique has been widely used to study the indoor airflow and contaminant dispersion over the enclosures. In this research, the effect of inlet air velocity on the ultra-clean ventilation system performance is investigated Eulerian-Lagrangian numerical approach. The results show that surgical wound contamination may be highly affected by inlet velocity. Thermal plume generated on the wound is responsible for protecting the wound from infectious particles and may be easily disturbed when inlet velocity goes over 0.1 m/s. This study and its results may be useful in getting a better understanding about airflow pattern in operating rooms equipped with the UCV system and in designing more effective ventilation strategies
