The Study of Water-Sediment Two Phase Flow Field Measurement Based on Particle Image Velocimetry

Abstract:

Internal flow field of water-sediment two phase flow was hardly observed by PIV system, due to poor light transmittance. To improve this situation, the glass particle was used in experiment instead of sediment particle. According to the experiment results, the light transmittance of the mixture of glass beads and water was better than the mixture of sediment and water; so the relatively clear internal image of the two-phase flow could be obtained by PIV system. According to the experiment, the glass beads movement was similar to sediment in water.
