Measuring the kinetic parameters of saltating sand grains using a high-speed digital camera被引量：5
《Science China(Physics,Mechanics & Astronomy)》2014年第6期1137-1143,共7页ZHANG Yang WANG Yuan JIA Pan 
supported by the National Natural Science Foundation of China(Grant No.11272252)
A high-speed digital camera is used to record the saltation of three sand samples(diameter range:300–500,200–300 and100–125μm).This is followed by an overlapping particle tracking algorithm to reconstruct the salt...

The wind-saltation interaction in a saltation boundary layer with a downwind air pressure gradient
《Research in Cold and Arid Regions》2010年第5期384-395,共12页ZhiBao Dong QingSong Mu GuangQiang Qian WanYin Luo 
the funding received from the Natural Science Foundation of China (40638038)
Studies of interactions between wind and saltating particles （i.e., the wind-saltation interaction） are usually conducted without consideration of the downwind air pressure gradient. However, in a wind tunnel with l...
