Dimensional analysis and experimental study of pressure drop and heat transfer for NaCl ice slurry in pipes.

Author(s) : ILLÁN F., VIEDMA A., MARTINEZ P.

Summary

Based on the dimensional analysis, the work reported in this paper try to determine which are the variables that explain the thermal and hydraulic behaviour of ice slurry, to fix the influence of these variables and to present the results so that they can be used as a tool of design for ice slurry applications. Experimental studies were performed to clarify the thermal and hydraulic characteristics of ice slurry with a 3% sodium chloride-water solution flowing in circular pipes. A number of experiments have been carried out to investigate the characteristics of flowing ice slurry for various pipe diameter, ice mass fraction, flow velocity and ice crystal size, and the nondimensional values have been obtained from the pressure drop (via Fanning factor) and the heat transfer (via Nusselt number). Experimental data on the friction factor are plotted on a Moody diagram. Experimental values of Nusselt number are plotted also versus Reynolds number and other parameters. Both data collections have been compared with other researcher's results, showing inmost cases a good level of agreement.
