Two timescales for longitudinal dispersion in a laminar open-channel flow
《Journal of Hydrodynamics》2017年第6期1081-1084,共4页王宇飞 槐文信 杨中华 季斌 
Project supported by the National Natural Science Foundation of China(Grant Nos.51439007,11372232)
At small dimensionless timescales T(= tD/H^2), where t is the time, H is the depth of the channel and D is the molecular diffusion coefficient, the mean transverse concentration along the longitudinal direction is n...

A random walk simulation of scalar mixing in flows through submerged vegetations被引量:12
《Journal of Hydrodynamics》2014年第3期343-350,共8页梁东方 WU Xuefei 
supported by the Non-profit Industry Financial Program of the Ministry of Water Resources (Grant No. 201401027);the China Scholarship Council
The scalar transport phenomena in vertical two-dimensional flows are studied using the random walk method. The established Lagrangian model is first applied to study the idealized longitudinal dispersion in open chann...
