Simulation of Pb++ Transport in Ferric Hydroxide Mineral

Explore the dynamics of Pb++ transport in ferric hydroxide mineral through simulation. Set domain size, gridding, and flow rate for accurate analysis. Utilize sorbing surfaces to study retardation effects. Simulation begins with clean water and ends after 10 years. Implement surface complexation dataset for insight into transport properties.

Presentation Transcript

  1. Specify domain’s starting fluid composition on the Initial pane Ferric hydroxide mineral Clean water Start, end of simulation

  2. Inlet fluid enters the domain from t = 0 to 10 years Inlet fluid carries Pb++and nonreactive Br− into the domain

  3. Specify domain size, gridding, and flow rate on the Domain pane. Domain is 1 km long, divided into 400 nodal blocks

  4. Set various mass transport properties on the Medium pane.

  5. File → Open → Sorbing Surfaces… Surface complexation dataset for hydrous ferric oxide. Mobility defaults to 0, indicating HFO is not transported. You can add any number of sorbing surfaces.

  6. Surface complexationretards Pb++transport relative to nonreactive tracer Br−.
