| Abstract: | An experimental investigation was conducted for the shell heat exchange characteristics of a dropper shaped tube heat exchanger by using the principle of heat mass transfer analogy and the technique of naphthalane sublimation,the influence of the arrangement forms on the average heat release and the change law of heat release coefficient with the rows in the direction of flow were discussed.The experimental correlative formula for calculating the average heat exchange coefficient of the bundles was given.The results showed that the dropper shaped tube bundles had an obvious advantage of enhanced heat transfer in comparison with circular bundles. |
