A comparison of three quantitative schlieren techniques
WebFeb 3, 2002 · Background Oriented Schlieren (BOS) is a widely used technique that provides density gradient information in flow fields of interest, without imposing stringent optical quality requirements on the facility/experiment windows and/or optics used in the BOS setup. Typically, the BOS reference image is acquired before the test begins (flow … WebABSTRACT. Imaging fluid flow and transport phenomena has gained considerable attention in the recent past. The imaging techniques are not only limited to visualization tools but, when coupled with suitable data reduction algorithms, can lead to the generation of the complete whole field quantitative data of flow and transported properties. WebJan 1, 2012 · These authors did an elaborate comparison of a quantitative color schlieren method with background-oriented schlieren (BOS) for the investigation of density fields in a supersonic wind tunnel. Both methods produced results within about 2% of the known theoretical curves, but BOS suffered in this comparison due to limited spatial resolution ... pay rate hike email to employer
