- Abstract:
- Vertical unidirectional flowing clean room is simulated by using fluent software，the streamline distribution，undistributed degree of velocity and sectional average wind speed of clean room are obtained．The simulation results show that，in therange of simulation，with the ratio of blowingarea increases，the inlet vor· tex decreases，thestreamline parallel degree becomes good，undistributed degree of velocity decreases．When the ratio of blowing area is 60％and70％，the inlet vortex is obvious．Whenthe ratio of blowing area is 80％，the inlet vortex is small，the streamline parallel degree meets the requirements of unidirectional flow．Velocity undistributed degree ofX=0planeandY=0 plane is 0．180 3 and 0．1940．1ess than0．3．Theav— erage wind velocity ofX=0plane and Y=0 plane is 0．335 4 m／s and 0．335 5 m／s．in the range of0．2～0．5 m／s，meets the design requirements of unidirectional flowing clean room．
