Data Center CFD Analysis - Case Study

Objective:

3D Model of a Datacenter with PAC Units

3D Model of a Datacenter with PAC Units

A Data center CFD Analysis is a facility that houses computer systems and associated components. It is challenging but important to optimize the flow paths of both cold supply air and hot return to minimize the mixing of these two streams as well as reduce any short-circuiting of cold air back to the air-conditioning systems. The objective of the CFD study is to predict air vel, RH & temperature distribution in the entire data center facility; assess airflow patterns around racks and identify areas of recirculation; and performance evaluation of individual components such as precision air-conditioning units and racks. Results can be used to reconfigure existing facilities to optimize the cooling and air distribution system.

As per the details received, the 3d model of the Data Center was modeled. After preparing the 3D model of the geometry, tetrahedral and hexagonal mesh with mesh sizes of 0.025 m to 0.3 m were created. False floor and false ceiling heights are also considered in the model. Cooling is to be provided using a raised flooring layout, and differentiation is done for the cold aisle and hot aisle. The heat source from the exterior wall according to the thermal resistance of the wall & heat source from n no. of server racks is ‘x’ MW, with each rack emitting ‘x’ kW of heat. Hot aisle and cold aisle diffusers are precisely modeled, fans installed, and details of obstructions inside the floor plenum and roof plenum are considered for the study.
