PRESSURE LOSS OF THE ICE/WATER MIXTURE IN THE HORIZONTAL AND VERTICAL PIPINGS : Studies on the ice/water mixture transportation for HVAC systems Part 1

Abstract

Ice/water mixture can transport much greater amount of cooling energy than ordinary water pipings. To find a basic flow characteristics of the ice/water mixture, the model experiments were performed and the results were analyzed based on the Froude Number to satisfy the model relationship. It was found that the pressure loss of the ice/water mixture was increased by the ice packing factor on the horizontal pipings and that the pressure loss was decreased on the upward flow and increased on the downward flow on the vertical pipings. As a result, the relationship between the Froude Number and the coefficient of additional pressure loss was presented for the plant design.
