| 摘 要： | 为了对船舶柴油机废气余热加以利用以达到船舶节能和减少碳排放的目的，结合船舶余热的特点，开展了船舶余热温差发电的数值模拟与实验研究。采用CFD方法完成了实验装置相关参数的选择后，进一步对温差发电装置的换热过程进行模拟，并通过实验验证了模拟的正确性。最后，以MAN/B＆W41V32/40式船舶主机为研究对象，对其废气余热温差发电的性能进行了评估。结果表明，在热端平均温度为500 K，冷端平均温度为310 K，冷却水流速为10 m/s的工况条件下，设计安装的1764片温差发电片输出总功率理论上可达31.75 kW。

| Abstract: | In order to recover the vessel exhaust heat for saving energy and reducing the carbon emissions, considering the characteristics of the vessel exhaust, the numerical simulation and experimental study of vessel exhaust based on TEG is conducted. CFD method is used for selecting the relevant parameters of the experimental device, the heat transfer process of the device is simulated and its correctness is verified. Finally, the MAN/B&W41V32/40 marine diesel engine is chosen for simulation in real ship condition, and the performance of its exhaust recovery based on TEG is evaluated. The results show that under the working condition which the cooling water flow rate is 10m/s, the average temperature of the hot side and the cold side is 500 K and 310 K respectively, the theoretical output of the device with installation of 1764 TE-module can reach 31.75 kW. |
