로터 간격 및 오일 유량을 고려한 스크류 압축기의 수치적 연구

초록

This study numerically investigates the effects of rotor clearance and oil injection on the thermal-fluid characteristics of screw compressors using SimericsMP+. The oil flow within the compressor is modeled using the Volume-of-Fluid (VOF) method, treating air as an ideal gas and oil as an incompressible fluid. Simulations are conducted with a deforming grid and standard k-ε turbulence model. The computational model is validated against reference data obtained under oil-free condition. Subsequently, a parametric study on rotor clearance and oil injection rate is conducted to analyze their influence on compressor performance and to identify optimal operating conditions.
