A novel prototype design of an internally geared twin screw compressor for air, with oil injection has been analysed using a custom developed numerical grid. A two-fluid Eulerian-Eulerian CFD model has been applied for the calculations. Compressor performance at various operating conditions has been evaluated together with an analysis of the flow at the suction, discharge, and injection ports. Over the calculated range of speed and pressure, a specific power of 2–4 kW/m3/min was estimated with a maximum volumetric efficiency of 95%. The adopted CFD model could be further used to optimize the oil injection and evaluate design modifications such as rotor profiles, variable lead rotors, etc.
