...Wen-Xiao Chu; Jui-Lin Wu; Yeng-Yung Tsui; Chi-Chuan Wang This study focused on the improved designs of airflow management in container data centers having overhead air supply. The computational fluid dynamics (CFD) model is first validated with experimental results. Then, the impact of grille...

... optimal strategy is adopted for which the computational fluid dynamics (CFD) results, artificial neural network (ANN), and MOGA are combined. The tubes elliptic ratio and Reynolds number are the design variables. The objective functions include Colburn factor (j) and friction factor (f). The CFD results...

...Georgios Karamanis; Marc Hodes We provide an algorithm to optimize the geometry of the fins in an array of longitudinal-fin heat sinks (HSs) in, e.g., a blade server, which is a prohibitively long task using computational fluid dynamics (CFD). First, banks of CFD simulations are run to precompute...

.... With the measured data of temperatures and airflow velocities, the mathematic model is constructed using a commercial Computational Fluid Dynamics (CFD) software and experimental data to present a comparison between test results and numerical simulations. The area of the data center is 311 square meters...

.... The computational fluid dynamics (CFD) software that is available has improved over the years. CFD software specific to data center thermal analysis has also been developed. This has improved the time lines of providing some quick analysis of the effects of new hardware into the data center. But it is critically...

... were divided into 4188 regions. All the regions have not only geometrical data such as coordinates and size but also effective anisotropic thermal conductivities. Inputting the attributes of all 4188 regions to the CFD software would be hugely time consuming. Although the inputting time would depend...

..., such as the manufacturing cost and the design freedom. More importantly, this study has provided a further step in the direction of demonstrating the opening effect. Comparison between experimental measurements and CFD simulation The temperature distribution on the substrate can provide more evidence for the CFD...
