Numerical Simulation and Wind Tunnel Experiment of Wind Field over Slope Surface
坡面地表下的风场的风洞实验与数值模拟

Current theoretical studies and numerical simulations of windblown sand movement concentrate on ideal circumstances,such as steady wind velocity,flat sand surface,etc.However,the environment of windblown sand movement is complex in natural environments,such as complex landform,turbulence structure of wind flow.Actually the gradient of the windward slope of the sand dune and the sand ripple etc.which are the basic form of the desert landscape,have great influence on the initiation and transportation of sand ...
