Hydroerosive grinding is used as a finishing and inlet rounding operation of diesel nozzles to improve the engine performance. A mixture of hard particles suspended in a carrier fluid circulates through the injection holes to remove material until the required flow condition is achieved, although the time to reach this specification increases with time. The aim of this study is to analyze the process efficiency without renewal of solid particles. Results show that the removal efficiency decreased 20% after 150 hrs and this significant loss can be attributed to hydrodynamic interactions, particle size distribution change, and fluid viscosity reduction.
