| Abstract |
Computational fluid dynamic (CFD) model was developed for predicting the effects of water temperature for producing ice in a box immersed in a pool containing brine water, the pool temperature and the pool side heat transfer coefficient on the water freezing time of the block ice box. Results from the model were agreed very well with those of onsite experiments of the conventional plant. The obtained model was used to predict the effects of the pool temperatures, the feed water temperatures and the pool side heat transfer coefficients ranging from -5oC to -20oC, 0oC to 40oC and 250W/m2oC to 50,000W/m2oC respectively on the freezing time of the block ice production having the dimension of 0.27 m x 0.56 m x 1.484 m. It was found that the pool temperature was the major factor. The minor factor was the feed water temperature whereas the heat transfer coefficient had not a significant effect. The freezing time decreased dramatically when the pool temperature not less than -7oC and gradually decreased until the temperature reached -12oC after that it fairly unchanged. The optimum pool temperature was suggested to be -10oC. At that pool temperature, the freezing time could be reduced from 45.20 hr to 44.24 hr when the feed water temperature reduced from 29.5oC to 5oC. The obtained results reveal the useful information for design and optimizing the plant operation which has not found in literature. |
