Abstract
Their most common mode of operation is as oil-flooded machines when delivering air and gases at moderate pressures and flow rates. In order to achieve the best performance, it is essential to be able to predict the optimum amount of oil, required for the oil injection process, accurately. Analytical procedures for the design and performance estimation of twin screw compressors are well developed. The Air-Oil separator (AOS), which is part of oil flooded rotary screw compressor, is modelled and CFD simulation is performed with the help of ANSYS Fluent. For the simulation of AOS finite volume discretization method is used. In case of highly swirling flow, the Reynolds Stress Model is used for better predictions. The results produced by this simulation are compared with existing AOS whose experiment data is collected. After validating the existing system, system is modified. The modification is done on geometrical parameter. CFD of the modified system is performed to predict flow behaviour, primary separation efficiency and pressure drop. The predicted values from CFD modelling are compared with experimental data. For different geometrical parameter, equation of primary separation efficiency in terms of pressure drop and angular position is formulated which is key outcome of this work.
