LASER DIAGNOSTICS:

The primary focus at the ARES is the development and use of tools which provide information on internal flows in engine assemblies. The internal flow diagnostic activity is primarily laser based and utilizes four approaches:

• Molecular Tagging Velocimetry (MTV)

• Laser Doppler Velocimetry (LDV)

• High Speed Flow Visualization (Flow Vis)

• Exciplex Fluorescence Imaging

Typically, a prototype test stand (or test rig) is built by the ARES and adapted for each experiment. With the aid of the test stand, one to all of the four laser diagnostic techniques listed above are implemented and provide for a qualitative/quantitative analysis of the observed flow.
