【摘要】 从连续介质流动的能量方程出发，推导了描述含沙水流的固液两相流的能量方程及能量耗散项表达式，并将能量耗散极值原理引入水轮机内含沙水流特性的研究中，从中得到了一些新的认识，并提出了一种全新的数学模型。参６更多还原

【Abstract】 The energy equation of silt laden flow and to dissipation function have been derived, based on the energy equation of continual fluid flow.In the meantime,the extremity law of energy dissipation rate has been introduced for the research of the silt laden flow and some deep insight obtained.Finally,a new mathematical model is developed.Refs 6.更多还原
