Experimental and numerical investigation of hospital surgery room air distribution through canopy

Abstract EN

This study present experimental and numerical analysis of airflow distribution through surgery operating room by using CANOPY.

The experimental work include an experimental operating room in laboratory of Babylon University.

Two cases were taken in analysis of air distribution.

Both cases have a ceiling air supply system and the different between then was in design of air supply system.

Both cases consist of patient bed, surgical staff around, overhead light, surgical light and electrical devices.

Air is exhausted through four exhaust grills located in four corners at latitude about 0.25 m from ground.

In numerical work a three-dimensional model of the experimental operating room was developed in Gambit and analyzed in FLUEN6.3.26.The results showed that ceiling system is a good ventilation system for air distribution in operating room.

Curtain air system gave more protection from laminar flow system where isolate the patient bed from the rest of the room and air velocity above the patient be low.

FLUENT program give a good and close results to reality .Good agreement between numerical and experimental results was obtained inside experimental operating room
