摘要

A Data Centre is a physical space that groups together computer equipment such as servers, storage arrays, among other equipment. It can be used for storage, processing and data protection. The majority of data centres operate 24 hours a day, and must provide the user with guarantees in terms of security and performance. Energy consumption is therefore permanent and the level of assistance and maintenance high. Data Centres have an ecological impact that is almost invisible to many users. In this paper a computational fluid dynamics (CFD) model of the airflow and thermal distribution of a real data centre room with 208 racks is proposed. Two case studies are presented and simulated with a high thermal load subjected to the minimum and maximum air flow velocity, respectively. The objective is to assess if the computer room air conditioning unit (CRAC) can cool the racks of the data centre in order to efficiently refrigerate all the hot spots.

7. We conducted experiments using a Solar-Sea-Oasis (SSO) and a microbubble generator (MB) toimprove hypoxic condition at mooring place in Tokyo University of Marine Science and Technology. We looked intoeffects of these apparatuses by computational fluid dynamics (CFD). When we operated SSO, the effect of dissolvedoxygen (DO) supply was only confirmed near the water outlet. This was suggested by computational fluid dynamicsthat water that came out from water outlet rising upward without staying in the bottom was the causes. Then, weconducted experiments using a MB to aerate bottom of the sea more directly. Vertical distributions of DO showedoxygen was supplied horizontally, but DO concentration increased about 0.24 mg L-1 that was lower than SSOexperiment. This was suggested by CFD that water came out from MB generator spread horizontally without stayingnear the MB generator was the cause. Therefore, it is necessary to improve of making the MB water staying morenear the MB generator. [O] . 遠矢亮, 小島諒子, 石丸隆, 2010
