Determination of the flow in the entrance area of a water vapour turbo compressor

摘要

Determination of the flow in the entrance area of a water vapour turbo compressor For R 718-water chillers with compressible, viscous flow in the sucking in area of the compressor; developed in the ILK, measurements in an air model and numeric simulation calculations are described. It is shown that the numeric supplies sufficiently exact results for velocities and temperatures, which are necessary e.g. for the sizing of and the inlet impellor.
