Hele-Shaw Cell

28

Pressure-controlled Hele-Shaw cell to conduct flow tests on 37.5 x 75 mm fracture analogs under different normal stress conditions. The cell is completely transparent and light transmission measurements are used to determine the in-situ aperture- and tracer concentration fields. Computer controlled confining pressure (up to 2MPa), pore fluid pressure (up to 2 MPa) and flow rate (up to 20 mL/min).
