Toward Active Control of Noise from Hot Supersonic Jets

Abstract

During this reporting period the first set of experiments were conducted successfully. In February, near-field and far-field acoustic measurements were made simultaneously for all jet conditions of interest. In April, the team was successful in integrating the MHz PIV system and performing synchronous data collection with the near-field and far-field acoustics. The April experiments also produced multi-exposure pulse-trace PIV images that may lead to a useful data analysis method for future use. CFD simulations are nearing completion and will shortly be ready for comparison to measurements.
