Dear Jirka,
I have to simulate the next experiment as follows:
- in situ experiment (di-pole test at a depth of about 350 m);
- horizontal groundwater flow and contaminant transport in clay rock (fractured): 110 cm;
- total period simulation, final time: 1440 minutes;
- Dirichlet (inflow); zero-gradient (outflow);
- constant concentration at inflow point for initial specific period and zero after the period;
- Darcy flow velocities, fixed value = 0.135 cm/min;
- total porosity = 0.3;
- matrix porosity = 0.137;
- fracture porosity = 0.163;
- diffusion in water [cm3/min] = 1.03E-3;
- fracture dispersivity [cm] = 2.8;
- matrix fracture interaction [1/min] = 2.3E-3;
- density of rock [g/cm3] = 1.42;
- pulse duration = 4.5 minutes;
- input concentration [mg/cm3] = 1.5
First, I have to simulate equilibrium model, then mobile-immobile or dual-porosity. I attached print-screen of my equilibrium simulation model, the graph dosen't look good at all and I don't know why.
