[Title of award-winning research]
The effect of the blending of carrier materials used in ore lifting on pump performance requirements

[Details of award-winning research]
Japan's territorial waters and exclusive economic zone contain untapped manganese nodules and seafloor hydrothermal deposits. The authors propose a carrier material circulation system as a method for lifting seafloor mineral resources. This system involves transporting capsules to the sea using a carrier material (a viscous fluid containing granular material, or CM) with high transport performance. In this carrier material circulation system, in order to determine the relationship between discharge pressure and flow rate, which is the performance requirement for the pump that pumps the CM, it is necessary to clarify the friction loss coefficient for each CM composition. Therefore, an ore-lifting model device was used to determine the friction loss coefficient for each CM composition. Furthermore, the relationship between discharge pressure and flow rate required for the ore-lifting pump was estimated.
