【 摘 要 】

Multiple topics will be discussed in this thesis involving a jet fuel and its equation of state. First, the types of jet fuels, equation of state, and past experiments and simulations will be discussed. Next, the equation of state of Jet Propellant 10 (JP-10) is explained. Furthermore, the effects of exposing JP-10 to high pressures and allowing expansion to occur via nozzle are simulated using a multi-physics simulation program called ALE3D. Specifically, the velocity and shape of high explosive initiated jets of JP-10 will be observed. Also, a parameter study will be performed to see how geometry and other variables effect these results. The simulation results are then compared to experimental results obtained and performed at the University of Illinois at Urbana-Champaign. The experiment is performed with multiple amounts of high explosive, jet fuel, and water for comparison purposes. Lastly, a numerical model will be developed and compared to the simulation results.
