abstract

Two-dimensional Laser Doppler anemometry (LDA) and computational fluid dynamics (CFD) are used to investigate the influence of cross-flow and momentum addition on flow features of a submerged entry nozzle (SEN) jet in a rectangular cavity (Rejet ≈ 95000). Round sidewall control jets are used to attempt to deflect and attenuate the main jet oscillation (St,W = 0.012). Feedback loop flow manipulation by injecting in the cross-flow region has shown to be an effective control configuration and a steady deflected jet has been computationally achieved. Higher control sensitivity has been observed for a variation on lateral jet momentum rather than for a variation of mass rate injected.
