Benchmarking background oriented schlieren against interferometric measurement using open source tools
Abstract
Gas flow from an under-expanding jet nozzle is measured using synchronized background oriented schlieren and interferometry diagnostics. The gas density distribution is obtained from a shift vector field of the background oriented schlieren and compared to the interferometric data. The comparison makes use of a simple calibration routine and open source Python recipes.
