The thesis " main studies and achievements are as follows : 1 . under the assumption of double - layer computational mode , the governing equations for the horizontal 2 - d stratified density current is derived by integrating the 3 - d fundamental equations along the flow depth . 2
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(dòng)基本方程。
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(duì)異重流運(yùn)動(dòng)近幾十年來(lái)的研究成果進(jìn)行較系統(tǒng)、全面論述的基礎(chǔ)上，針對(duì)目前研究較為前沿的異重流運(yùn)動(dòng)數(shù)值模擬問(wèn)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(jiǎn)化的基礎(chǔ)上，對(duì)黃河流域劉家峽水庫(kù)中的異重流運(yùn)動(dòng)和排沙進(jìn)行了二維數(shù)值模擬，結(jié)果令人較為滿意。
