...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...

... dynamics (CFD) software, during the design stage. PCBs are chiefly composed of copper ( 398   W / m   K ) patterns and epoxy ( 0.3   W / m   K ) insulator. The thermal conductivity of copper is more than 1000 times that of epoxy, so heat diffusion via the copper...
