Based on particle phase dynamics

the Euler-Euler model in FLUENT was selected to numerically simulate the ice slurry flowing in a piping system such as a straight pipe

90° elbow pipe

and T type pipe without considering the ice melting process. The simulation results revealed that the pressure drops in these three pipe types at the entrance were obvious. In the 90° elbow pipe

the inside pressure was less than the outside pressure after the bend

and the highest and lowest pressures appeared in the shunt of the T type pipe. The ice slurry flow experiment results showed that the specific pressure drop increased with the velocity and ice particle fraction. Among the three pipe types

the pressure drop of the straight pipe was the smallest

and that in the T type pipe was the largest. A comparison of the numerical simulation and experimental results showed that the pressure drop was consistent with the flow velocity within an error range of 20%

but the simulated value was larger than the experimental value at high flow rates. Determining the flow characteristics of an ice slurry will play an important role in the popularization of ice slurry engineering applications.
