ABRASIVE WEAR IMPROVING OF BLADES ON EFFICIENCY OF BLADE ROW OF AXIAL-FLOW COMPRESSOR STAGE
Journal Title: Проблеми тертя та зношування - Year 2016, Vol 71, Issue
Abstract
In work the results of numerical modeling of abrasive wear improving of axial-flow compressor blades on the losses due to viscous friction are presented. Abrasive wear reduces efficiency. When the regular roughness has relative height 0.002-0.005 efficiency is decreased by 3%, with a further increasing the roughness relative height to 0.01 efficiency is decreased by 8% as compared with the efficiency of smooth axial-flow compressor blades.
