Results of the IES Cleanroom Flow Modeling Exercise

Six contributed solutions to the Cleanroom Flow Modeling Exercise sponsored by the IES Computer Applications/ Cleanroom Modeling and Evaluation Working Group are compared with each other and with experimental data obtained in a cleanroom configuration similar to that defined in the exercise. Quantitative comparisons are given for time-averaged airflow velocity magnitude and direction and particle concentration. The good agreement between the measured and computed velocity results shows that numerical models can accurately predict the flow pattern in this configuration. However, the particle concentration agreement is not as good.
