  7. Abstract:
  8. Cleanrooms have a broad scope of applications from electronics, pharmacy, biotechnology to hospital industries, and are susceptible to fine and ultra-fine particles. In this work operating room in the category of hospital applications is chosen. Airborne particles in the operating room depends on many factors such as room geometry, inlet and outlet design, air displacement rate, obstacles, etc. Surgical light is one of the most critical obstacles in the operating room as it is upstream to the surgery zone. The study presented in this thesis aimed to numerically investigate the influence of radiation emitted from the medical lamps on the indoor airflow quality in operating room environment. For this purpose the Fluent (6.3.26) simulation tool is utilized for modeling such heat transfer phenomena. S2S radiation model was chosen among five available radiation models in Fluent because of its reliability in modeling enclosure radiative heat transfer for nonparticipating media. Based on the results it was determined that by increasing the velocity of inlet airflow, generated thermal plume over the surface of lamps had become weake. Also results indicated that by increasing the power of lamps, generated thermal plume over the surface of lamps become much stronger. Likewise result showed that generated thermal plume over the surface of the lamps was stronger when radiation was applied in the modeling
