Abstract
Starting and buzz characteristics of high-speed intakes were investigated with nanoparticle injection. Isentropic and Kantrowitz contraction limits were estimated at particle mass loading ratios of 0, 0.12, and 0.24 using a simplified one-dimensional numerical model. Eulerian–Lagrangian simulations of a two-dimensional external-compression intake with an operating Mach number of two were performed. Simulations were conducted at particle mass loading ratios of 0, 0.12, and 0.24; and nozzle throttling ratios from 0.57 to 0.44. The effects of nanoparticle injection on the Ferri-type instability and unstart were investigated through synthetic schlieren visualization and spectral analysis of pressure and shock motion. A novel method of eliminating buzz by varying the size of injected particles was also discussed.
