流れ場中の粒子による配管表面摩耗モデルの提案とその評価〔流体工学, 流体機械〕

A new erosion model and rebound coefficient was proposed by a modification of Finnie's theoretical approach. The present erosion model includes the effects of impingement velocity, impingement angle, particle density. Main features of the model are as follows : (1) The erosion rate is proposed to the particle velocity cubed. (2) The relationship of the impingement angle and the erosion rate is in good agreement with author's experimental data.
