Application of Two Sections Focusing Schlieren Technique on the Supersonic Combustion Wind Tunnel
Recently, the research of flow structure of hypervelocity athodyd firebox is very popular , especially, to realize the three dimension flow structure of cut layer and eddy is more exigent, therefore, many flow visualization techniques have been developed, such as the particle image velocimetry (PIV). The focusing schlieren method is good in three dimension flow visualization for it needn’t put any materials in the flow [2, 3, 4], The focusing schlieren system to show the flow fields of two sections in the research of hypervelocity firebox fuel branch wake structure has been developed, which can be used also to validate the ability to show the three dimension flow. The system can get two images of two different sections flow at the same time in one experiment, if the technique has been breached, it will be used to show more sections is promising.
