HEAT TRANSFER OF ICE SLURRIES IN PIPES

Some basic ideas of the heat transfer of ice slurries are discussed. The equations des-cribing a flow of a Bingham fluid through a tube with a heat flux over the boundary are presented. The theory shows that familiar Relations known in the field of heat exchangers, e.g. the logarithmic-mean temperature difference, do not always apply. – With a device, designed to measure the heat transfer coefficients in tubes, first exper-imental data on the specific heat capacity have been obtained. They are compared with model results. The velocity profile of a laminar ice slurry flow has been mesured with an ultra-sound velocity profile sensor. Furthermore, ice particles of a water/etha-nol ice slurry have been observed under a microscope.
