Abstract
To study the performance and estimate the oscillating bearing loads of a tw in screw air compressor, a theoretical model is proposed in this paper. Bas ed on the model, a computer simulation program is developed and effects of different design parameters such as rotor profile, geometric clearance, oil injected position, oil temperature, oil flow rate and other operational co nditions are investigated. Output variables such as bearing loads, specific power, compression efficiency, volumetric efficiency, discharge temperatur e are obtained. Some of the results are then compared with experimentally m easured data, and good agreements are found between the simulation results and the measured data.
