Research Highlights:

  • Use CFD software, FLUENT, to generate detailed data as numerical experimental data
  • Use CONTAM in the data assimilation toolbox: OpenDA
  • Forecasts are made in the time frame of days in terms of airflow infiltrations and indoor contaminant levels
  • Different data assimilation methods will be tested within OpenDA
