NUMERICAL AND EXPERIMENTAL STUDY ON TURBULENT DIFFUSION FIELDS IN CONVENTIONAL FLOW TYPE CLEAN ROOMS.

Author(s) : MURAKAMI S., KATO S., SUYAMA Y.

Summary

TURBULENT FLOW FIELDS OF VELOCITY AND DIFFUSION IN SEVERAL TYPES OF CONVENTIONAL CLEAN ROOMS ARE PRECISELY ANALYZED BOTH BY MODEL EXPERIMENT AND BY NUMERICAL SIMULATION. THE DETAILED ANALYSES OF CONTAMINANT DIFFUSION BY SIMULATION MAKE IT POSSIBLE TO COMPREHEND CLEARLY THE STRUCTURES OF VELOCITY AND DIFFUSION FIELDS IN CLEAN ROOMS. THE FLOW FIELDS IN SUCH ROOMS ARE MAINLY CHARACTERIZED BY THE INFLOW JET AND THE RISING STREAMS AROUND IT. THE COMBINATION OF ONE JET AND RISING STREAMS FORMS A < FLOW UNIT >. THE TOTAL VELOCITY FIELD AND THE RESULTING DIFFUSION FIELD OF CONTAMINANT IN A ROOM ARE WELL MODELLED AS SERIAL COMBINATIONS OF THESE < FLOW UNITS >.
