Abstract
This present study experimentally investigates the rheology and drag reduction characteristics of ice slurry flow in the spiral and circular pipes, to allow visualization of the flow regimes. For comparison, the tests were conducted for flow transition from laminar flow to turbulent flow in the spiral and circular pipes. During the tests, the ice mass fraction varied from 3% to 21%. The experimental results demonstrated that the ice slurry flow in the spiral pipe, considering turbulent flow, exhibited lower friction factor compared to that in the circular pipe. Additionally, the drag reduction rate of the spiral pipe was approximately 25%. Furthermore, visualization diagrams of the ice slurry flow in the circular and spiral pipes were also proposed. Concerning the transport prospect of the ice slurry flow, the experimental results showed that the spiral pipe produces the best drag reduction results for ice slurry flow in the turbulent regime due to engineered geometric patterns of the conduit.
