Optical Diagnostics with Background Oriented Schlieren : A practical perspective on reactive and non-reactive flow scenarios
The oldest and without a doubt one of the most versatile non-intrusive measurement approaches is the schlieren imaging technique. Although they have been used over a century for visualization of flow fields, they are associated with certain drawbacks. In this regard, background oriented schlieren (BOS) provides a unique opportunity to quantitatively characterize density varying flows which has a m
