Magnetic field coupled velocimeters

The velocimeter R&D program entered a "bench-top' scale experimental demonstration phase with the construction of a first prototype velocimeter drive-pickup coil array, a propane combustor test stand, and Z-80 based data acquisition/processing system. A computer code was written and successfully tested which modeled the response of the velocimeter array to flow field structures that could be realized on the test stand. Conventional diagnostics have been used to characterize the flow environment produced on the test stand. Preliminary testing of the velocimeter was begun at the end of the program year. Problems with signal detection and analysis were tentatively identified and possible solutions were under design.
