摘　　要：微型涡轮是气缸排气能量回收转换装置的核心部件。为了分析不同工作条件下微型涡轮所受压力、扭矩以及蜗壳内的流场分布情况,通过实验及Fluent仿真模拟,深入研究了不同涡轮叶片数量、不同风帽形式下对微型涡轮叶片表面分布压力、扭矩及蜗壳内流场分布情况的影响规律,进而设计一种使涡轮叶片所受压力均匀,产生大扭矩的微型涡轮结构,并给出了涡轮叶片数量与所受压力及所输出扭矩的函数关系,为进一步微型涡轮发电系统集成奠定了理论基础。The micro-turbine is the key component of the pneumatic cylinder＇s exhausted-air reclaiming devices. In order to analyze the pressure, the torque and the flow field distribution of the micro turbine under different working conditions, we study the influence of different numbers of turbine blades and different cap forms on the micro tur- bine blade surface distribution of pressure, torque and flow field distribution in the volute by experiments and simu- lation by the software Fluent. Then a new turbine blades is designed to produce high torque, and the function rela- tionship between the number of turbine blades and the output torque is given.
