国内渔船出海作业一般采用碎冰对渔获物进行保鲜，不但传热效果差，而且碎冰的尖角经常会刺破鱼体，保鲜效果较差。由于冰浆具有良好的流动性和较大的蓄冷密度，因此在渔获物保鲜中具有良好的应用前景。基于动力学理论的欧拉双流体模型，利用粒子流与传热传质模型相结合的方法，研究了冰浆的流动和传热特性，在采用文献数据对计算模型进行验证后，对方管内冰浆与渔获物的流动传热进行了计算研究，对比分析了水平方管内的冰浆在不同入口体积分数、不同流动速度下与方形渔获物的传热情况。结果显示，冰颗粒的分布情况是影响其与渔获物表面传热的主要因素，随着冰颗粒入口体积分数的提高，渔获物上表面与侧面的热通量整体有所增大；随着入口冰颗粒体积分数的增大，其在渔获物表面的分布趋于均匀。同时发现，适当提高流动速度可以增大渔获物表面冰颗粒的体积分数，从而增加表面热量交换。

Crushed ice, which is usually used on domestic fishing vessels to keep the fish fresh, has poor heat transfer effect, and its sharp corners often pierce the fish, resulting in a poor freshness retaining effect. On the contrary, the ice slurry has a good application prospect in fish freshness retaining due to its good fluidity and large cold storage density. Based on the Eulerian two fluid model of dynamics theory, this paper studies the flow and heat transfer characteristics of ice slurry by using the method of combining particle flow with heat and mass transfer model. The flow and heat transfer between the ice slurry and the fish in the square tube is calculated and studied based on the verification of the calculation model by using the literature data. The heat transfer performances between ice slurry and square fish in horizontal square tube at different inlet volume fractions and different flow velocities are compared and analyzed. The results show that the distribution of ice particles is the main factor affecting the heat transfer between them and the surface of the fish. With the increase of the inlet volume fraction of the ice particles, the heat flux of the upper surface and the side of the fish increases. With the increase of the inlet volume fraction of the ice particles, the distribution on the surface of the fish tends to be uniform. In addition, it is found that increasing the flow velocity can increase the volume fraction of the ice particles on the surface of the fish, thus increasing the surface heat exchange.
