Result description
The development of dense fluids required for unconventional pumped hydro by means of using fine coal waste from three case studies was analysed: a dense fluid with a density up to three, in order to achieve a yield up to three times that of the conventional pumped hydro.
Results:
- a) A small surfactant (less than 1%) should be added to prevent the slurry from coalescing and improve flow.
- b) In all cases, in the viscous response and in the range of shear rates that were accessible, it was observed that viscosity decreases with increasing shear rate.
- d) The dumpsite minerals from the mines are initially attractive as base materials for dense fluids. Two of the samples showed values in the interval bounded by our contrast formulations, which have already been used to prepare dense fluids.
