The Compact Modeling of Raised-Floor Stanchions

Stanchions (also referred to as jacks, posts, or pedestals) support the raised floor system common to most data centers.  These small-scale objects are often omitted from CFD models of data centers because they are thought to have negligible impact on airflow or because of the increased computational effort required to model them explicitly.   This presentation discusses how and why stanchions should be included in data center simulations.   A compact modeling approach is proposed which is based on a combination of experimental data and a new analytical model.  The model is validated by detailed CFD simulation and actual data center measurements.
