Abstract
Numerical Study of Patient Respiration Effect on Bacterial Dispersion in a Surgery Room
Highlights
A cleanroom is usually considered as an environment with minimum amount of environmental pollutants with respect to the regular level of a closed environment, which is necessary to produce products or carry out scientific and industrial researches
It is evident that the existence of a peak in each cycle was related to the maximum amount of output bacteria at the end of the inhale stage
The respiration influence on the particle concentration in a selected surgery room was numerically investigated in this study
Summary
A cleanroom is usually considered as an environment with minimum amount of environmental pollutants with respect to the regular level of a closed environment, which is necessary to produce products or carry out scientific and industrial researches. Dating back to more than one hundred years ago, designing and manufacturing of cleanroom originated from the efforts to control the spread of the viruses and diseases in hospitals. Cleanrooms have numerous applications in modern industries [1,2,3,4,5,6,7]. According to ISO standard 14644-1, a cleanroom is a space where the concentration of the particles is controlled, constructed and operated in a way that the admittance, generation, and settlement of the particles in the environment are minimized [8]. Many numerical studies focus on determining the effective parameters such as the particle distribution in a cleanroom, since considering these parameters is crucial in the design and fabrication process. For accurate assessment of the condition of the flow circulation, it is essential to determine the particle concentration distribution [9, 10]
