Density and temperature reconstruction of a flame-induced distorted flow field based on background-oriented schlieren (BOS) technique
Project supported by the Key Program of the National Natural Science Foundation of China (Grant No. NSFC 91441205).
(color online) Schematic diagram of the BOS technique. The black dash line represents a ray from a background point through the flow field without density gradient to the imaging plane, the red solid line denotes a ray from the same background point through the flow field with density gradient to the imaging plane.
