   在異重流雙層計(jì)算模式下，從三維水沙基本方程出發(fā)，利用數(shù)學(xué)工具沿垂線積分，推導(dǎo)得出了平面二維異重流上、下兩層水體的水沙運(yùn)動基本方程。
2. After a comprehensive review on the study of sediment density current in the recent several decades , a set of differential equations for 2 - d density current under double - layer computational mode is established . by simplifying th . set of equations , a 2 - d numerical simulation of sediment density current and sediment outflow has been made in the liujiaxia reservoir in the yellow river basin , and the result is reasonable
   本論文在對異重流運(yùn)動近幾十年來的研究成果進(jìn)行較系統(tǒng)、全面論述的基礎(chǔ)上，針對目前研究較為前沿的異重流運(yùn)動數(shù)值模擬問題，提出了一套二維異重流雙層計(jì)算模式下的基本方程，并在這套方程簡化的基礎(chǔ)上，對黃河流域劉家峽水庫中的異重流運(yùn)動和排沙進(jìn)行了二維數(shù)值模擬，結(jié)果令人較為滿意。
