空气涡轮机和相关的供气管被优化为牙科空气涡轮机手机系统。该系统由带有叶轮和外壳的空气涡轮机以及向空气涡轮机提供压缩空气的供气管组成。使用 ANSYS CFX 研究了牙科空气涡轮手机系统的流动特性。该研究旨在找到重要的设计参数，并根据最大扭矩对其进行优化。选择叶片数量、叶轮叶片角以及叶轮与壳体之间的间隙作为三个主要设计参数。实验技术设计用于优化两种牙科空气涡轮手机系统：类型1是单独的空气涡轮，类型2是带有供气管的空气涡轮。优化结果表明，对于类型1，叶轮与壳体之间的间隙不是重要参数。类型2的最大扭矩低于类型1。两种类型的优化后的最佳叶片数相同，但两种类型的叶片角度和间隙不同。刀片角度和刀片数量对于类型 1 很重要，所有三个设计参数对于类型 2 都很重要。类型 2 的性能改进比类型 1 更大。根据噪声水平、旋转速度和拔出力的实验测量，对两种优化手机系统的性能进行了审查。
An air-turbine and associated air supply tube was optimized as a dental air-turbine handpiece system. The system consists of an air-turbine with an impeller and a housing, and an air supply tube which supplies compressed-air to the air-turbine. The flow characteristics of the dental air-turbine handpiece system were investigated using ANSYS CFX. The study aimed to find the significant design parameters, and optimize them in terms of the maximum torque. The number of blades, the blade angle of the impeller and the gap between the impeller and the housing were chosen as the three major design parameters. The design of experiment technique was used to optimize two dental air-turbine handpiece systems: Type 1 was an air turbine alone and Type 2 was the air-turbine with an air supply tube. The optimization results showed that the gap between the impeller and the housing was not a significant parameter for Type 1. The maximum torque was lower for Type 2 than for Type 1. The optimized optimum blade number was the same for both types, but the blade angle and the gap differed between the two types. The blade angle and blade number were significant for Type 1, and all three design parameters were significant for Type 2. The performance improvement was greater for Type 2 than for Type 1. The performance of both optimized handpiece systems was reviewed in terms of the experimental measurements of noise level, rotational speed, and withdrawal force.
