This paper summarizes the results of an experimental study of airflow rates through perforated tiles in a raised-floor data center. Flow rates are presented for various configurations of perforated tiles under different scenarios for the computer room air conditioning (CRAC) units. The measured airflow rates for selected cases are compared with those given by a computational fluid dynamics (CFD) program. The two sets of results are in good agreement.
