1. Plans For ARIES-IFE Study Farrokh Najmabadi ARIES Conference Call May 17, 2000 Electronic copy: http://aries.ucsd.edu/najmabadi/TALKS ARIES Web Site: http://aries.ucsd.edu/ARIES

2. Analyze and asses integrated and self-consistent IFE chamber concepts; Identify the design/operation window for each promising concept; Identify present data base and need extrapolations for each promising concept; Identify high-leverage items for R&D. Note: the research is not aimed at developing a point design. ARIES Integrated IFE Chamber Analysis and Assessment Research -- Goals

3. The research is not aimed at developing a point design. The goal is to understand trade-offs and identify design windows. To guide the R&D, we need to be clear on what are high- leverage R&D items: –Not only What data is missing and what are shortcomings of present tools if any? –For incomplete database, what is being assumed and why? –For incomplete database, what is the acceptable range of data? Would it make a difference to zeroth order, i.e., does it make or break the concept? Scientific Credibility is the key. ARIES Integrated IFE Chamber Analysis and Assessment Research -- Goals

4. To make progress, we divide the activity based on three classes of chambers: –Dry wall chambers; –Solid wall chambers protected with a “sacrificial zone” (such liquid films); –Thick liquid walls. These classes of chambers will be researched in series with the entire team focusing on the task in hand. We choose a minimum of two and a maximum of four target designs for analysis. For a start, we choose designs that are already produced in detail. (5 classes of target are identified.) ARIES Integrated IFE Chamber Analysis and Assessment Research -- Approach
