Abstract

An experimental investigation was carried out to determine pressure drops of the flow of a two-phase mixture of spherical ice capsules and water inside the pipelines of cooling systems. Instead of ice capsules, spherical capsules made of polypropylene material whose density (870 kg/m(3)) is similar to that of ice were used in the experiments. Flow behavior of the said spherical capsules, 0.08 m outer diameter, was observed in the measuring section inside plexiglass pipes, 0.1 m inner diameter and 6 m in length; pressure drops were measured on the 4 m section. The investigation was carried out in the 1.2 x 10(4) < Re < 1.5 x 10(5) range and under transport concentration (C-tr) by 5-30%.
