MODELOVÁ CIRKULACE FLUID V EXPERIMENTÁLNÍ NÁDOBĚ MOCK-UP-CZ
Roč.22,č.1-2(2015)
Mathematical modelling confirmed the probable formation of the convection cells along the heater with variable velocities depending on the hydraulic and thermal properties of the bentonite mixture and on the physical properties of the saturating fuid. The generated flow field could be the driving force for the geochemical non-homogeneities.
