Validation of a Semi-Empiric Model for Twin-Screw Compressors with an Adaptable Internal Volume Ratio

Twin-screw compressors with an adaptable built-involume ratio can significantly increase the overall process efficiency for applications with fluctuating operating conditions. Detailed component models, necessary to assess their full potential, are rare in literature. Therefore, this work develops and validates a novel semi-empiric compressor model taking into account the mechanical adaptation of the built-involume ratio. The model shows good agreement with operating data provided by the manufacturer.     «
