Abstract
This research work deals with design, fabrication and assembly of a two axis traverse system to make various non-intrusive planar measurements as applicable to aero propulsion research in the stream wise and span wise direction. The Two axis Traverse system will help enable the investigators to address various types techniques and acquire detailed and comprehensive information about the flow field which may be a single plane flow field where the fuel-air mixing of the gas jets can be studied by acquiring the velocity field of the injected fuel at various stream-wise reactions using Mie scattering technique or alternatively study the liquid penetration and mixing characteristics by the use of appropriate lasers and image acquisition equipment. This traverse will also enable studies on drop size characteristics in a liquid fuel spray and fluorescence studies on the spray for fuel fraction measurements by mixing additional attachments to the image acquisition like an image doubler for SMD studies and image intensifier for fuel fraction measurements. The functionality of the traverse is verified and demonstrated by making planar Mie scattering measurements in subsonic cross flows for spray penetration.
