Presentation Transcript

  1. Initial chemical composition and temperature can vary across the domain. Click on a “+” button to enter heterogeneity data for any field variable: • enter data node by node • import a table • use a script, equation, or function • enter an average value and standard deviation

  2. Nodal block spacing can be regular or refined in the areas of greatest interest.

  3. Choose to enter porosity data node by node.

  4. Import a table with porosity values for each node. Alternatively you can enter tables in-line from the command pane.

  5. Use a simple equation to describe the porosity field. Or write a BASIC script or C++ function for the most flexibility. Thermal conductivity and internal heat sources can vary in space, as can longitudinal and transverse dispersivity.

  6. Porosity is set in this run to vary randomly according to a Gaussian distribution. Permeability is set to vary with porosity.

  7. Br− enters the fluid through the left boundary. The random porosity and permeability structure create a “fingering” pattern of infiltration.
