Importance of the Return Air Opening to Degree of Turbulence in an I-Grade Clean Operating Room

摘要

In this paper, a high Reynold K- ε two equation model has been used. The range of return air openings that can be used has been induced by numerical simulation to influence the return air opening and degree of turbulence in an I-Grade clean operating room in conditions that insure a degree of cleanliness and supply velocity. The size of the return air opening has been analyzed by comparing the results of the numerical simulation and experiment. The results will help the design of the I-grade clean operating room.
