Optimal airflow management can save 50% cooling energy for data centers as demonstrated in our new journal paper about our open source Fast Fluid Dynamics model for fast prediction of data center airflow. The paper is available here. Funded by DOE's BENEFIT program, this is a joint effort of SBS Lab with Schneider Electric. The FFD model has been adopted in Schneider Electric's data center design tools. The open source version and related papers are available on the FFD tool page. Congratulations to Xu on publishing this paper and we look forward to more great work from you!
