摘要：

Erosive wear due to solid particles is an undesirable phenomenon. It causes structural failure directly or in combination with fatigue or corrosion. This generally is more serious in rotating machinery of all types mainly the blades of hydro, steam and gas turbines. However, there are positive aspects of this unwanted phenomenon, which in this paper, are utilized for investigation of boundary layer growth, separation and reattachment of separated now. In the present investigation, flow visualization of two-dimensional objects viz., circular, aerofoil and hydrofoil based on above concept has been described.
