Abstract

This paper focuses on the geometric characterization of a specific rotor profile for twin-screw machines, based on a method proposal that can be successfully applied to reproduce any patented or absolutely new profile. At first, the profile generation is explained by means of the necessary theory, supported by the basic mathematical equations. Later, some specific results are presented. They are the sealing (contact) line, the cusp blow-hole area, the inter-lobe area and the cavity volume evolutions. In detail, the cavity volume is strictly linked to the displacement, whereas the sealing (contact) line length and the blow-hole area represent two major paths for fluid leakages. All the geometric calculations have been carried out by means of original scripts and are preliminary to next thermodynamic simulations.This paper focuses on the geometric characterization of a specific rotor profile for twin-screw machines, based on a method proposal that can be successfully applied to reproduce any patented or absolutely new profile.

双螺杆压缩机主要几何特性研究

本文着重于双螺杆机器的特定转子轮廓的几何特征，基于一种方法建议，可以成功地应用于复制任何专利或绝对新的轮廓。首先，在基本数学方程的支持下，用必要的理论解释了剖面的生成。最后，给出了一些具体的结果。它们是密封(接触)线、尖端气孔区域、叶间区域和空腔体积演变。具体而言，空腔体积与位移密切相关，而密封(接触)线长度和气孔面积是流体泄漏的两个主要途径。所有几何计算都是用原始脚本进行的，为下一步的热力学模拟做了准备。本文着重于双螺杆机器的特定转子轮廓的几何特征，基于一种方法建议，可以成功地应用于复制任何专利或绝对新的轮廓。首先，在基本数学方程的支持下，用必要的理论解释了剖面的生成。最后，给出了一些具体的结果。它们是密封(接触)线、尖端气孔区域、叶间区域和空腔体积演变。具体而言，空腔体积与位移密切相关，而密封(接触)线长度和气孔面积是流体泄漏的两个主要途径。所有几何计算都是用原始脚本进行的，为下一步的热力学模拟做了准备。
