Numerical simulation of sandy bed erosion by 2D vertical jet被引量：21
《Science China(Technological Sciences)》2011年第12期3265-3274,共10页HUAI WenXin WANG ZengWu QIAN ZhongDong HAN YaQiong 
supported by the National Natural Science Foundation of China (Grant Nos.10972163,51079106));the Fundamental Research Funds for the Central Universities (Grant Nos.2104001,2103002)
A two-dimensional numerical model of vertical jet scour was developed based on the turbulent flow theory and jet scour mechanism. In this model, drag force acts as the main reference variable and the critical Shields ...

Analytical solutions for transverse distributions of stream-wise velocity in turbulent flow in rectangular channel with partial vegetation
《Applied Mathematics and Mechanics(English Edition)》2011年第4期459-468,共10页槐文信 耿川 曾玉红 杨中华 
supported by the National Natural Science Foundation of China (Nos. 10972163 and 51079102);the Fundamental Research Funds for the Central Universities (No. 2104001)
The theory of poroelasticity is introduced to study the hydraulic properties of the steady uniform turbulent flow in a partially vegetated rectangular channel. Plants are assumed as immovable media. The resistance cau...
