摘要：
Ice slurry is a kind of energy-intensive phase change fluid, and knowing the flowing properties of ice slurry is of paramount importance to engineering applications. With the ice slurry conveying system inside a horizontal pipeline as the research object, by the combination of the solid and liquid two-phase flow non-Newtonian rheological theory and experimental testing, the non-Newtonian rheological property and resistance property shown by the ice slurry under such conditions as different conveying speeds, different concentration of ice particles and different pipe sizes are researched. The research results reveal the following conclusions: the rheological properties of ice slurry flow meet the power-law rheological characteristics, the rheological coefficient increases with the increase of ice particle concentration and pipe diameter, while the rheological index will present the opposite variation law. Meanwhile, the variation of the rheological parameters directly affects the distribution of the resistance properties of ice slurry flow. When the flow speed is low, following the increase or decrease of the rheological coefficient, the resistance coefficients of ice slurry flow inside the pipeline show a significant difference.
