  21. Chamber Technology Achievements in FY02/03 MTOR allows experiments on MHD fluid flow in self-cooled liquid metals, and free-surface liquid walls. • Facilities were constructed and operated to address liquid breeder MHD in both free-surface and closed channels. • Sophisticated and complex computer code development is underway for 3-D modeling of fluid flow. • Established a temperature window in which a liquid wall can operate within an MFE reactor with a high exit coolant temperature for power conversion. • Explored advanced solid wall blanket concept with potential to improve the attractiveness of fusion power plants. • Obtained experimental results of the effective thermal properties of beryllium packed beds. FLIHY addresses key issues and innovative techniques for enhancing heat transfer in low-conductivity fluids in closed channel flows.
