EVALUATION OF COMMERCIAL CFD SOFTWARE PACKAGES
A study was conducted to successfully implement a commercially available CFD software package for the thermal, fluid, combustion, and/other transport-phenomena analysis, design, development and testing of the client’s products and services. This study was divided into two Phases:
Phase I: Evaluation of CFD software implementation
Brief survey of the current commercially available CFD software packages
- In-depth assessment of the current and future thermal, fluid, combustion, and/or other transport-phenomena analysis, design and development needs of the client. Special attention will be focused on the reduction of testing and prototyping deployment times of current and future products for all of the client’s engineering subject areas. This will include conducting in-depth surveys and interviews of current client’s engineering personnel to assess their needs and wants in relation to CFD software applications.
- Matching of current CFD software packages with the current and future thermal, fluid, combustion, and/or other transport-phenomena analysis, design and development needs of the client. Furthermore, assessment of the pro’s and con’s of the each evaluated CFD packages will be carried out, including the computer system/network hardware and software requirements for the CFD package implementation.

NOVEL CRYOGENIC COOLING SYSTEMS FOR HIGH POWER CHIPS
The purpose of this work is to develop a novel technology to cryogenically cool high power computer chips such as the PentiumTM and ALPHATM chips in an efficient, low cost, low volume manner. This involved the unique combination of individual technologies that separately have been proven to be effective in the thermal management of electronic systems, but together might solve the problem of cooling high power components to cryogenic temperatures. The goal then was to design a cryogenic thermal management system capable to remove high heat loads (from 500 W to 1500 W) in relatively small volumes that feature PentiumTM and ALPHATM CPU chips.
