| Abstract: | The fundamental theory for the pressure fluctuation is described and the wall pressure fluctuation in high velocity sediment laden and aerated flow is measured.Based on the experimental data,an investigation is made on the characteristics of pressure fluctuations in the three phase flow of water,air and sand.The effects of air concentration and sediment content on the amplitude and frequency of pressure fluctuations are discussed. |

| Keywords: | sediment laden flow aeration presure fluctuation spectrum analysis |
