  6. What did we do? (1/6) CFD software for cleanroom: CAMETA version 2.0 Time-independent (steady-state) solution Three-dimensional domain Cartesian coordinate system Physical quantity of interest: Airflow velocity

  7. What did we do? (2/6) Cleanroom test case

  8. What did we do? (3/6) Cleanroom test case: z = -1.7 m

  9. What did we do? (4/6) Cleanroom test case: z = -4.8 m

  10. What did we do? (5/6) Cleanroom test case: y = 0.6 m

  11. What did we do? (6/6) Cleanroom test case: y = 1.0 m

  12. What are we doing? (1/1) CFD software for cleanroom: CAMETA version 3.0 Time-independent (steady-state) solution Three-dimensional domain Cartesian coordinate system Physical quantities of interest: Temperature distribution Relative humidity distribution Particle concentration distribution

  13. What do we dream of? (1/1) Cleanroom-embeded-software control system CFD software = Visualizing as numerical sensors Online sensors = Physical sensors where needed Supercomputer = ~ Real time computing for CFD Benefits Automatic control system No disturbance & contamination into cleanroom Detailed information inside cleanroom Infrastructure for nanotechnology

  14. What research area needed? (1/1) Turbulence Modeling Scalar-Transport-Phenomena Modeling: Temperature (Heat) %RH (Humidity, or Moisture Content) Particle Concentration Fast and Adaptive Computing Algorithm Grid and Cluster Computing Sensor, Measurement & Instrumentation
