Numerical Analysis of Perforated Plate Use for Cooling Data Center and Server Room

Airflow management is essential for the efficiency of cooling systems in data centers. Numerical approach is useful in the analysis of proposed body force model of data centers either before construction or with existing infrastructure. Perforated plates are significant in several applications because of their abilities to regulate heat and fluid. It is important to address basic problems about how the shape of holes and the void percentage of plates influence fluid flow. The present paper incorporates comparison of different turbulence models for orifice plate simulation and modifications have been made to the tile flow model to account for the flow dynamics through the perforated tile. This analysis is confined to the zone above the floor, where allowable air flow rates at the tile intake is defined. Mathematical model porous jump model and body force model are used to compare the numerical result. The parametric investigation is also done to obtain the design parameters. To check the effect of porosity of perforated plate with respect to the homogeneity of the flow, different porosity 30%, 40%, and 50% of the perforated plate porosities are analyzed.
