Cantera Outline

Overview of Cantera

• Capabilities
  • High level division of Cantera's capabilities
  • Zero-D, One-D, phase objects, numerics

• Division of capabilities should roughly follow how Cantera source code is divided
  • Apps - utilities for converting between Chemkin and Cantera file formats, parsing input files, comparing output files, etc.
  • Base - more utilities for array storage, printing and logging, XML file parsing, Cantera errors/exceptions,
  • Clib - code for C API
  • Converters
  • Equil
  • Fortran - code for Fortran API
  • Kinetics - classes for getting/setting/calculating reaction network quantities (net production rate source terms, reaction rate parameters, etc.)
  • Matlab - code for Matlab API
  • Numerics - classes for solving ordinary differential equations, evaluating Jacobians, Newton methods, constructing and solving matrices, etc.
  • OneD - classes relating to one-dimensional simulations (domains, stacks, one-dimensional flame simulations, etc.)
  • Python - code for Python API
  • Spectra
  • Thermo
  • TPX
  • Transport
  • ZeroD - classes relating to zero-dimensional Reactors (Reactor, Wall, etc.)

Kinetics

• Discussion of kinetics
  • Separate from reactors themselves
  • Reaction rate source terms
  • Kinetic mechanisms
  • Single phase kinetics
    • Source code abstraction
    • Examples of obtaining reaction rates
    • Graphene - how to really USE this information
  • Multiphase surface kientics
    • Surface coverage, site density, formulation of approach
    • Source code abstraction - Walls vs. SurfPhase vs. (etc.)

• Kinetics for reactor design
  • Integral reactors (canonical CHE reactors)
  • Differential reactors (initial value problems, marching in time)
  • Integral catalytic reactors
  • Differential catalytic reactors

Thermodynamics

• Somewhere in our algorithm, looping over domain (or for the single reactor control volume), and we're saying, "update thermo and transport parameters" - focus on how this is being done, what classes its using, what capabilities are available

• Single phase
  • Mixtures
  • Equations of state
  • Equilibrium
  • Piston-cylinder systems

• Multiphase
  • What thermodynamics is there for multiphase systems?
  • Heat transfer to-from surface

Transport

• Follow BSL a bit on this one...

• Mass transfer
  • Diffusion
    • Mixture vs. multicomponent diffusion
    • Diffusion coefficient models
  • Mass transfer coefficients

• Heat transfer
  • Heat diffusivity
  • Heat transfer coefficients

• Momentum transfer
  • Viscosity

• General discussion: non-dimensional analysis, how it relates to cantera
