Accurate computation of the cooling of data centers is a challenging multiscale problem with scales spanning several orders of magnitude. Several hierarchical levels of models have been developed in the literature. These range from network based models to more complex turbulent CFD models based on Reynolds-averaged formulations. In this paper, we summarize these approaches, and describe some techniques to significantly accelerate the CFD models. Three techniques, namely the multigrid method, multilevel refinement, and GPU based parallel computing, are described.
