dc.description.abstract The paper aims to capture the rack level thermal dynamics in data center. It proposes the rack level response experiments as well as transient CFD analysis to characterize the local thermal environment of the system. A single sever simulator rack and its two neighboring racks with its cold and hot aisle containment has been modeled with known cold air supply temperature and flow-rate for transient CFD analysis. The heat load was kept constant initially and varied case to case basis that includes capturing the rack level response with respect to changes in input. However, the response experiments on simulator rack were performed for 14 hours by variation of server heat loads as step and ramp input. The paper provides the detailed transient CFD analysis of data center racks. The local cold air flow rates and temperature at the vicinity of the racks showed significant effect due to changes in input. It was concluded that the rack level dynamics impacts the thermal environment of data center & hence cannot be ignored. The high computing devices and faster internet demands have led to major thermal management concerns for data center operators. To tackle this issue, capturing the system thermal dynamics is imperative. However, the system level CFD analysis is computationally expensive. Therefore, this paper deals with the rack level transient CFD study using commercial tool STAR CCM+. This paper includes the modeling of the servers as a porous media as well as the multi-grid method to enhance the computational speed. The successful implementation of this approach validated through experiments. This would help to establish a base for research in any type of data center. This paper provides the porous media approach to model servers & multi-grid method to enhance the computational speed. At the same time, the thought of characterizing the local dynamics at the vicinity of data center racks is unique.
