Computational analysis of ejector with oscillating nozzle.

Number: pap. 2326

Author(s) : ARUN K. M., TIWARI S., MANI A.

Summary

Present study numerically investigates the effect of oscillation of convergent-divergent nozzle in an ejector using ANSYS Fluent.15.5. The nozzle domain will oscillate between two points in the ejector at particular frequency and amplitude. The motion of nozzle and movement of the mesh according to the nozzle oscillation is made possible by user-defined functions available in ANSYS Fluent 15.5. Variation of entrainment ratio with time has been studied at different amplitudes and frequency combination and the same is compared with the stationary nozzle. Even though the oscillating nozzle underperforms the conventional one at lower amplitude and frequency, the former one shows a trend of increasing with increasing frequency.
