Fundamentals of Equations of State

When: August 19 – 20, 2014

Instructor: Dr. Gerald Kerley, Kerley Technical Services

Location: Johns Hopkins University, Homewood Campus, Baltimore, MD

About the course:

The course presents a broad overview of equation of state (EOS) theories and modeling techniques, covering both foundations and applications. It is suitable for graduate students as well as professional scientists and engineers who are seeking a greater understanding of these topics. The contents of the course are as follows:

  • Basic Concepts: The definition of an EOS and material state; the phenomena that control material behavior; the main approaches to material modeling; the role of experiments; and the scientific disciplines that are used in creating EOS.
  • The Continuum Point of View: The equations of continuum flow; shock wave propagation; thermodynamic principles; and the treatment of both equilibrium and non-equilibrium phenomena.
  • The Molecular Point of View: The use of quantum mechanics in EOS modeling, with emphasis on special problems; the definition of ensembles in statistical mechanics and how they are used to derive the continuum equations; thermodynamic perturbation theory, chemical equilibrium, and ionization equilibrium.
  • EOS Modeling Techniques: Application of the above foundations to create sophisticated EOS models that include solid-solid phase transitions, melting and vaporization, changes in chemical structure, and thermal excitation of electrons.
  • Specific Materials: Examples of EOS for metallic and non-metallic elements, compounds, plastics and polymers, composite materials, and ceramics.
  • Applications: How EOS models are used in hydrocode calculations and other problems; porosity; material strength issues.
  • Topics for the Future: Suggestions for following up the course and problems needing further work.

About the instructor:

Gerald Kerley received a B.S. degree in chemistry (Ohio University, 1963) and a Ph.D. degree in chemical physics (University of Illinois, 1966). He served as a U.S. Army officer, assigned to the Defense Atomic Support Agency, from 1967 to 1969. He was a technical staff member at both Los Alamos National Laboratory (1969-1984) and Sandia National Laboratories (1984-1995). From 1995 to 2005, he worked as a scientific and technical consultant, serving DOE and DOD laboratories and contractors. In 2006, Kerley cut back on his consulting work to study basic scientific problems of personal interest.

Dr. Kerley has extensive experience in applying the methods of quantum mechanics, statistical mechanics, and thermodynamics to problems of practical interest. Most of his professional career has been devoted to modeling equations of state (EOS), explosive behavior, and other material properties for use in hydrocodes, and to using these models in numerical simulations of hydrodynamic and shock-wave phenomena. His accomplishments include the following:

  • He is the author of the PANDA and EOSPro codes, which offer sophisticated theoretical models for constructing EOS for all types of materials over a broad range of conditions.
  • From 1976 to 1978, he was the principal designer and developer of the SESAME library at Los Alamos, a database of EOS tables specifically designed for use in computer codes.
  • In 1991, he developed a new and more general SESAME EOS package that was installed in the Sandia 3-D Eulerian code, CTH.
  • He developed the HVRB model, which describes the shock initiation and detonation of explosives.
  • During his ten years as a consultant, he taught seven short courses in EOS modeling techniques for hydrodynamic calculations.
  • He has made significant contributions to the theories of liquids and mixtures, electron correlation, QM perturbation theory, and improvements to the Born-Oppenheimer approximation.

Information for course attendees:

If you are traveling by car, visitor parking is available in the South Garage. If you are using a GPS system for directions, the best address to use in 3101 Wyman Park Drive.  We will have parking vouchers available when you arrive.

All of the course events other than the Tuesday afternoon Social will take place in Hackerman Hall room B-17 (lowest level) .  The Social will take place in the Malone Hall first floor lobby. A campus map and course schedule are attached. Malone Hall is the newest building on campus and too new for this map so it is marked with a big pink X, in between Mason (1) and Hackerman (11).
