Numerical Investigation and Performance Evaluation of Laminar Ventilation Systems for Operating Room

EasyChair Preprint 2137

Abstract

Many emerging trends in the healthcare facilities such as evolution of treatment resistant bacteria and immune compromised patients is continuously contributing to post operative surgical site infection (SSI) in Hospitals. To control this, the only effective option left with us to maintain the infectious particle free environment in the operating room. This can be achieved by using effective ventilation system. Vertical Laminar airflow ventilation system is proved to be the most effective among others to achieve the same.

In this paper three configurations of laminar airflow ventilation systems have been evaluated in the view of controlling SSI using Computational Fluid Dynamics.

Results show that the laminar ventilation system having inlet air diffuser array covering entire ceiling area (Case-1) exhibits excellent performance but it is not feasible as the sizing of the laminar flow array. Laminar ventilation system with limited area of diffuse array located over the critical area and exhausts are located at bottom of both the walls opposite to each other (Case-2) exhibits performance near to performance of Case-1.
