Abstract
Three-dimensional flow characteristics in a liquid fuel ramjet combustor are investigated using PIV method. The combustor has two rectangular inlets form 90 degree each other, having intake angles of 30 degree. Three guide vanes are installed in each rectangular inlet to improve the flow stability. The experiments are performed in the water tunnel test with the same Reynolds number as the case of Mach 0.3 at the inlet. PIV software is developed to measure the characteristics of the flow field in the combustor. Accuracy of the developed PIV program is verified with rotating disk experiment and standard data. The experimental results show that the two main streams from the rectangular intakes collide near the plane of symmetry and generate two large longitudinal vortexes, which is consistent with three dimensional computational results. A large and complex three-dimensional recirculating flow is measured behind the intakes.
