Thermal Properties Card Syntax (EOR)

STOMP-EOR solves a conservation of energy equation that considers heat transport via conduction through the rock/soil grains and pore-filing fluids, heat transport via fluid advection, balanced by changes in the internal energy of rock/soil grains and pore-filing fluids. The Thermal Properties Card allows the user to specify thermal conductivity models and parameters and the specific heat of the rock/soil. Thermal properties specified through this card are considered to be intrinsic properties of the rock/soil

Input Data Types

Character string (e.g., van Genuchten, porosity, m^3/s, Roe Superbee)

Integer (no alpha characters, special characters, or punctuation) (e.g., 1, 32, 195634)

Real (decimal points and exponential notation allowed) (e.g., 0, 0.0, 1.e-12, 1.E+3, 2.345)

Keyword (exact formatting required) (e.g., file, ~Solution Control Card, binary file)

Card Title

~Thermal Properties Card,

Thermal Conductivity Model, Directional Parameters, and Specific Heat

Repeat

Repeat for each rock/soil type

Info

IJK, JKI, or KIJ Indexing

Expand for Syntax

If Rock/Soil Name is IJK Indexing, JKI Indexing, or KIJ Indexing then a parameter value can replaced with an external file using the following formatting for ASCII files:

...,file:file name,...

or binary files:

...,binary file:

file name

,...

The external file will contain parameter values for every grid-cell ordered according to the indexing scheme (i.e., IJK, JKI, or KIJ). Units shown in the input line will be applied to all parameters in the external file.
