Rack level transient CFD modeling of data center

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. This paper deals with the rack level transient CFD study using commercial tool STAR CCM+. A single sever simulator rack with its cold and hot aisle containment has been modelled with known cold air supply temperature and flow-rate. The detailed server thermal mass and porous boundary conditions were implemented through literatures. The significant transient effects on the streamlines and thermal profile has been observed due to variation of heat source.
