Molecular tagging velocimetry in the wake of an object in supersonic flow

Molecular tagging velocimetry in the wake of an object in supersonic flow Molecular tagging velocimetry using air photolysis and recombination tracking (APART) was applied to the wake flow of a 30° wedge in a small Mach 3 wind tunnel. Average velocities could be determined with a standard deviation down to 0.4% (free stream) and 7% (expansion fan behind wedge). Instantaneous velocities (measurement time 7 µs) could be recorded with a standard deviation down to 2%, limited by the available laser power. The measured velocity profile behind the wedge is compared to a simulation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

Molecular tagging velocimetry using air photolysis and recombination tracking (APART) was applied to the wake flow of a 30° wedge in a small Mach 3 wind tunnel. Average velocities could be determined with a standard deviation down to 0.4% (free stream) and 7% (expansion fan behind wedge). Instantaneous velocities (measurement time 7 µs) could be recorded with a standard deviation down to 2%, limited by the available laser power. The measured velocity profile behind the wedge is compared to a simulation.
