Chapter 14 - The Equation of State and Chemistry at Extreme Conditions: Applications to Detonation Products

Abstract

The chapter explains the equation of the estate and chemistry at extreme conditions as applied to detonation products. Laboratory products conducted on materials held in excess of several kbar provide insight into a realm of chemical material properties that are significantly different from those encountered under ambient conditions. Dynamical simulation based on approximate Bonn–Oppenheimer potentials plays a large and increasingly important role in chemistry and in the biological and materials sciences. The chapter reviews the recent efforts to combine experimental and theoretical efforts to refine our knowledge of interatomic potentials and chemical processes at extreme conditions of pressure and temperature. The accuracy of the equation of state of polar fluids is significantly enhanced by using multi-species or cluster representation of the fluid. The methods to measure sound velocities of various super critical fluid systems are presented. The study of chemistry and kinetics of fluid under extreme conditions is explained with the help of the diamond anvil cell and the presence of CH2O2 during the detonation of some common explosion. Further resources are also provided.
