Multi-Component, Multi-Point Interferometric Rayleigh/Mie Doppler Velocimeter
An interferometric Rayleigh scattering system was developed to enable the measurement of multiple, orthogonal velocity components at several points within very-high-speed or high-temperature flows. The velocity of a gaseous flow can be optically measured by sending...
Briefs: Physical Sciences
A capability for real-time computational simulation of aeroheating has been developed in support of the Hyper-X program, which is directed toward demonstrating the feasibility of...
