Experimental Study on Deck-Temperature-Rising Technology in Different Deck Area

Deck-temperature-rising technology is the new technology that solves the antifreeze and deicing problems of ship deck. In this paper, the special experimental device was designed, and the influence laws of this new technology in different deck area were studied. Comparative experiments were done with the deck area at 18*22cm2, 26*22cm2 and 32*22cm2. The experimental results show that with the same initial temperature of water and deck surface, the deck area has significant impact on this new technology. The larger the deck area is, the greater the warming amplitude and the better warming effect can be achieved. For example, the warming amplitude is about 1.7°C as the deck area is 32*22cm2, while the warming amplitude is only about 0.6°C as the deck area is 18*22cm2. This conclusion will be valuable in further studies on this new technology.
