SYSTEM FOR CREATING GAS-FLOW FIELD DATABASE AND SYSTEM FOR PREDICTING DIFFUSION STATE OF DIFFUSION MATERIAL

WIPO Patent Application WO/2010/055765

A1

A long-term wide-area gas-flow field data operation unit (101) obtains hourly gas-flow field data of one year by an RAMS or the like by using weather data of global weather reanalysis data (G) as the entrance boundary condition for the computational region.  An atmospheric stability calculation/addition unit (102) obtains the stabilities of the representative gas-flow field data of the respective gas-flow field data and adds the obtained stabilities to the respective gas-flow field data.  A wind direction-based/atmospheric stability-based classification unit (103) classifies the respective gas-flow field data into cases with different combinations of wind directions and atmospheric stabilities.  A wind direction-based/atmospheric stability-based gas-flow field database creation unit (104) selects gas-flow field data that are representative of the respective cases and associates the selected representative gas-flow field data with the respective cases with the different combinations of wind directions and atmospheric stabilities, thereby creating a high-precision gas-flow field database at reduced operation load.
