METROSION - Metrology to Enable High Temperature Erosion Testing

In this paper a description of the modelling of a nozzle for high temperature solid particle erosion and the comparison of theoretical results with experimental data has been provided.

A new high temperature solid particulate erosion test system has been designed at the National Physical Laboratory to improve the quality of high temperature erosion tests. The new test system is designed to carry out experiments at temperatures up to 900 °C andparticle velocities up to 300 ms −1 . This has been achieved through the careful design of the nozzle, balancing the gas flow, gas pressure and nozzle geometry to achieve the design goals. The nozzle design has been carried out using multi-physics Finite Element Modelling to analyse the gas flow and temperature.
