Abstract.
Fluorocarbon liquids have very low sound speeds in comparison with water. The measurement of shock waves in water is complicated by its relatively high sound speed. This paper presents a fluorocarbon liquid with a sound speed of 655 m/s for use in liquid shock experiments. Experimental and numerical results of shock wave reflection from various parabolas and wedges are given. Experiments were performed in a vertical liquid shock tube. The properties including an equation of state for the liquid are given. Numerical simulations using this equation of state are performed using a finite element program. It is shown that the investigation of non-linearities in water will require shock tubes that can withstand high pressures. Due to the high B/A parameter for this fluorocarbon liquid, it is demonstrated that non-linearities can be achieved and studied at much lower pressures.
