New Fourier-Reynolds correlations for refrigeration applications

In this paper, the development of new Fourier-Reynolds correlations for determining the cooling process parameters of products subject to air cooling, in terms of the half cooling times and seven-eighths cooling times is presented. The experimental data were taken from the author's previous work, processed and used in the development of new Fourier-Reynolds correlations and diagrams. These Fourier-Reynolds correlations are FOH = 42.465Re(-0.54426) and FOS = 125.21Re(-0.53913) for half cooling times and seven-eighths cooling times, respectively. The results of this study indicate that there is a strong relationship between the Fourier and Reynolds numbers, and the Fourier-Reynolds correlations and diagrams are simple and effective tools for determining the cooling process parameters for such objects cooled in air flows. It is believed that these could be beneficial to the refrigeration industry. (C) 1997 by John Wiley & Sons, Ltd.
