Performance of components of ice slurry systems: pumps, plate heat exchanger, fittings.

Author(s) : NØRGAARD E., SØRENSEN T. A., HANSEN T. M., et al.

Summary

The performances of different multiple-stage centrifugal pumps have been measured with ice concentrations in the range of 0 to 30 wt. % of ice. It was found that the pump operation is reliable in the entire range of ice concentrations. The pump performance decreases with increasing ice concentration due to the increasing viscosity of ice slurry. The viscosity model proposed by T.M. Hansen et al., (2000) has been applied to compare the manufacturers' data on the viscosity dependency. The flow behaviour of ice slurry has been investigated in a test rig with transparent pipes to allow visual observation of flow patterns in various single components such as fittings, valves and heat exchangers. Finally, pressure loss coefficients in selected fittings have been measured to reveal the dependency of ice concentration.
