Bi-Directional System Coupling for Conjugate Heat Transfer and Variable Leakage Gap CFD Analysis of Twin-Screw Compressors

Autor: Nikola Stosic, S Rane, Ian K. Smith, A Kovačević

Publikováno v: IOP Conference Series: Materials Science and Engineering. 1180:012001

Oil-free twin-screw compressors are essential in various industrial applications where clean compressed gas is required. Due to the absence of the cooling oil in these machines, thermal deformations are large. Hence, design clearances are generally s
