  • Cavitation and cavitation erosion in cryogenic fluids [Elektronski vir]
    Dular, Matevž
    Optimal operation of turbopumps is crucial for all liquid fuel rocket engines. To reduce weight, these pumps often operate at critical conditions, where dynamic instability and cavitation are ... unavoidable. Many studies were already performed to investigate these phenomena, yet, due to the complexity of the measurements, most avoid experiments in cryogenic fluids. Hence no data on thermodynamic effects of cavitation or on the specifics of cavitation erosion in cryogenic fluids exist, what threatens further progression of technology. In the talk I will show experiments in cryogenic fluids where cavitation is initiated acoustically % by ultrasound. We characterized the development, the dynamics and the physics of cavitation and erosion on an ultrasonic horn, which was operated at elevated pressures in liquid nitrogen.
