The turbulent characteristics of high - velocity sediment - laden and aerated flow are more other than the clear water flow of single - phase and current of low speed . in a special circulating system with high velocity flow , some flow parameters such as boundary shear stress and pulsation pressure are measured . an investigation is made on the turbulent characteristics of the three - phase flow of water , air and sand 本文针对高速含沙掺气水流的运动规律有别于低速水流及清水单相流，在自己研制的高速浑水循环系统中，通过对高速含沙掺气水流壁面剪切应力和脉动压强等参数的量测，分析了水沙气三相流的紊动特性，探索了泥沙对固壁的磨蚀机理及减蚀措施，其主要内容包括以下几个方面： 1
