摘　　要：涡轮机是海洋能转化利用过程中重要的机械结构,能够将流体的动能转换为旋转的机械能,带动发电机运转发出电能,已经广泛地应用于海洋能发电领域。传统意义上的叶片涡轮结构较为复杂,使用时容易发生工作介质泄露等问题,这将很大程度上降低涡轮机的使用效率。特斯拉涡轮机因结构简单、制造公差要求较低、密封性好等优点又重新回到了研究者的眼中。特斯拉涡轮机的运行性能决定着能量转换效率的高低,研究发现,特斯拉涡轮机目前转换效率还不算高,在工程实践应用中还无法大量普及,因此提高特斯拉涡轮机的使用效率就尤为重要。文中对影响特斯拉涡轮机运行性能的因素进行了归纳与分析,介绍了特斯拉涡轮机的机械结构、应用领域和研究现状,列举了国内外研究人员对特斯拉涡轮机进行的实验以及研究,总结了特斯拉涡轮机的数值模拟方法,为提高特斯拉涡轮机的能量转化效率和在日后的实际应用中提供一定的参照依据,最后展望了特斯拉涡轮机在小型海洋能利用装置上的应用前景。Turbine is an important mechanical structure in the process of ocean energy transformation and utilization,which can convert the kinetic energy of the fluid into rotating mechanical energy and drive the generator operation to generate electricity,which has been widely used in the field of Marine energy power generation.In the traditional sense,the blade turbine structure is a little bit complex,easy to use the working media leakage and other problems,which will greatly reduce the efficiency of turbine use.Tesla turbines due to simple structure,low manufacturing tolerance requirements,good sealing and other advantages are back in the eyes of researchers,and the operating performance of Tesla turbines determines the level of energy conversion efficiency,through the study found that Tesla turbines are not yet high conversion efficiency,in engineering practice applications can not be widely used,so it is particularly important to improve the efficiency of tesla turbines.This paper summarizes and analyzes the factors affecting the performance of Tesla turbines,introduces the mechanical structure,application field and research status of Tesla turbines,lists the experiments and studies carried out by researchers at home and abroad on Tesla turbines,summarizes the numerical simulation methods of Tesla turbines,provides some reference basis for improving the energy conversion efficiency of Tesla turbine and in future practical application,and finally looks forward to the application prospects of Tesla turbines in small marine energy utilization devices.
