On Investigating the Hydrodynamic Field for Jets with and without Installation Effects

Abstract: Near-field hydrodynamic and acoustic characteristics of an unheated subsonic jet with chevron nozzles were investigated experimentally with and without jet installation effects. Near-field pressure fluctuations were acquired for Mach numbers ranging from 0.3 to 0.9 for four different types of chevron nozzles in an anechoic jet facility at the University of Bristol. The measurements were carried out on an axial microphone array traversed in the radial direction and placed close to the jet. The tests were perfor… Show more

“…Installed jet configuration and flow condition are based on the experiments performed at the Bristol Jet Aeroacoustic Research Facility (B-JARF) at the University of Bristol, where the isolated jets are placed close to the flat plate [13].The test facility is well validated for a wide range of mach numbers [26][27][28][29]. The experiments were carried out for a round convergent nozzle (SMC 000) and four chevron nozzles.…”

“…Near-Field Hydrodynamic Pressure Fig. 11 shows the comparison between the experimental measurement [29] and the LES calculation to validate the nearfield hydrodynamic pressure field for isolated SMC000 and SMC006 at Mach number of 0.5 and 0.9. The hydrodynamic pressure spectra are plotted at two locations corresponding to 𝑥/𝐷 𝑗 = 6.0, 𝑦/𝐷 𝑗 = 2.0 and 𝑥/𝐷 𝑗 = 14.0, 𝑦/𝐷 𝑗 = 3.0.…”
