Our laboratory work is focused on analysing mixing processes in different types of natural and artificial porous media. Experiments are conducted under controlled light conditions using optical methods with different cameras and mostly conservative dye tracers.
Currently, our inventory includes 2 transparent plexiglass flow chambers: one with variable width, measuring 100 x 50 x 1.2 cm in its longest structure, and a small one measuring 50 x 15 x 1.2 cm. Both are equipped with lateral connections to allow the injection. Thanks to the modular design, wall elements can be changed without time expenditure, enabling the addition of measuring sensors or further injection points.
In our flow chambers, experiments can take place both under stationary and transient flow conditions. For this purpose, we are equipped with two modern 4-channel and one 16-channel peristaltic pump with which we can precisely regulate flow velocities. In addition, we have a small technical workshop at our disposal, as well as equipment and material for density measurements, sieve analyses and spectrophotometric measurements. At the moment, we also have an SIP device for geoelectrical measurements on loan.
