Abstract

This paper describes the use of a rotating all mirror image de-rotator system in collaboration with Particle Image Velocimetry (PIV) to visualise and examine qualitatively the flow patterns within a clear acrylic model of a ShockWave Power GeneratorTM (SPG-TM). The authors have been able to obtain the relative velocities of the flow within the SPG-TM unit at rotational speeds of 1,000 rpm. Vector maps of the relative flow field in the pertinent areas are presented for this rotational speed. The data is compared with the results of a Computational Fluid Dynamics (CFD) model and appears to show a reasonable correlation.
