*1-D Model of Roots Type Supercharger
Original language description
*This paper introduces research work on 1-D model of Roots type supercharger with helical gears using 1-D simulation tool. The main objective of the work is to describe Roots charger features and to amend Roots charger design. The presented analysis toolis a 1-D model of Roots type supercharger respecting inlet and outlet processes due to the change of volume between teeth, fast compression in the gap between teeth after connecting the compressor outlet, mass flow losses caused by teeth mesh and casingclearances and additional compression/expansion between meshing-in teeth. Finding the geometrical data (variable volumes, surfaces and cross-section areas) is based on newly developed procedures using scripts in 3-D solid CAD model, in which teeth meshing was simulated. The developed model has been calibrated using supercharger map measured at a test rig. The model constructed from 1-D model modules has been used for sensitivity analysis considering design data.
