Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.
The experimental analysis of a titanium plate heat exchanger using ice slurry as cooling medium has been carried out at our laboratory. The ice slurry was produced from an ethylene glycol 10 wt% aqueous solution. The pressure drop and heat transfer performance has been measured in an experimental test ring. In the paper, the characteristics of the plate heat exchanger and the experimental facility are described in detail. The heat transfer
perfurmance of the heat exchanger has been determined fur different ice slurry flow rates and different ice fractions. The pressure drop measurements are presents as a function of mass flow rate and ice concentration. Moreover data of heat transfer rate, overall heat transfer coefficient and pressure drop operating with water and with ethylene glycol solutions are presented. The experimental results are discussed in the paper.
