INVESTIGATION OF HEAT EXCHANGE DURING MOVEMENT IN A HORIZONTAL TUBE OF AN AQUEOUS PROPYLENE-GLYCOL ICE SLURRY

摘要

A test method for investigating the heat-transfer coefficient as a function of the concentration of ice crystals in an ice slurry, the ice slurry flow rate in a tube, and the tube heat-flow density was presented. The experimental results were given. Comparative tests were carried out with a single-phase aqueous propylene glycol solution of the same initial density as the liquid from which the ice slurry was prepared. Keywords: ice slurry, horizontal tube, heat-transfer coefficient, calorimetric method, concentration, flow rate.
