surface liquid metals are being investigated as heat removal surfaces in fusion
reactors. This project will develop
non-invasive diagnostics to study the flow characteristics of these systems,
(including film thickness distribution, velocity distribution, and
fluctuations). The measurement will
be non-intrusive and use frequency modulated Doppler laser radar.
An infrared laser beam will be reflected off the liquid surface through a
vacuum window in the fusion chamber to conduct the measurements.
The free surface flow diagnostic device will be designed to operate in
the fusion environment that involves high magnetic field, high temperature,
vacuum, and electromagnetic interference. In
Phase I, feasibility study of the concept will be carried out, taking into
account the complications introduced by the fusion environment.
A conceptual design of the complete diagnostic system will be developed.
Commercial
Applications And Other Benefits as
described by awardee: The diagnostic system should be useful for the
non-intrusive precision measurement of range, velocity, and surface features of
all surfaces, including surfaces with low (1%) reflectivity.
It also should have applicability to moving surfaces like free surface
liquid metal flows as well as to stationary surfaces.
