This paper will describe two recent advances in Computational Fluid Dynamics (CFD) modeling as it pertains to data center design. In particular, the paper will define the use of the Capture Index (CI) in data center analysis, and will discuss the importance of accurately modeling coolers. Secondly, the article will describe Mentor Graphics' own $30M data center project currently in development. Two...
The optimization of cooling resources within data centers (DCs), which includes the localized provisioning of cooling power with respect to the heat dissipation, can lead to significant reduction of energy consumption. While such matching is rather straightforward for the entire DC, on a more granular level however, the large range of heat densities of today's IT equipment has made this task much...
Open-type double-skin facades (DSF) depend on natural ventilation without any mechanical devices. In order to study thermal performances of the open-type DSF, principles of energy saving and heat transfer procedure of this facade are illustrated through theoretical analysis; a computer modeling is conducted by use of Computational Fluid Dynamics (CFD) technology, in which changes of environment temperature,...
This paper discusses experimental and theoretical results for several embodiments of pulsed air jet technology. Pulsed air jets, also called synthetic jets, require an implementation strategy that is quite different from steady-flow devices such as fans and blowers. Simply replacing a fan with a synthetic jet will most likely result in a failure to cool a device as intended. The principal goal of...
