Flow in a model of the SSME main injector bowlMean-flow and turbulence quantities obtained in a 32-percent acrylic model of the SSME main injector bowl are presented. Flow visualization obtained with laser sheets and conventional photography shows the basic patterns and identifies regions of recirculating flow. Measurements of mean-flow and turbulence normal stresses are obtained with laser velocimetry to confirm these results and to quantify flow characteristics in the inlet ducts, entrance region, racetrack, LOX-post bundle, and exit nozzle. Measured velocity distributions show the upstream effect of the injector bowl in the transfer ducts, the plenum effect of the racetrack and LOX-post bundle, and the nonuniform distribution of flow into the main exit nozzle.
