Résumé

Local measurements of the axial mixture velocity and ice fraction profiles were conducted for the vertically, upward adiabatic ice slurry flow in a rectangular channel using a hot film anemometer (HFA) and an on-line ice slurry sampling/calorimetry technique. Experiments were performed at area-averaged ice fractions and mean velocities. The ice fraction distributions systematically displayed slight peaking near the adiabatic walls for average ice fractions less than 8%; however, at higher ice fractions, the ice fraction distributions became flatter. For average ice fractions greater than 2%, the velocity distributions displayed flatter profiles than in single-phase flow, which indicates the non-Newtonian flow characteristics of ice slurries.
