The geometric factors which influence airfoil aerodynamic performance are attributed to variations in local first- and second-order curvature derivatives. Based on a self-developed computational fluid dynamics (CFD) program called UCFD, the influence

Compared with a drag-type vertical axis wind turbines, one of the greatest advantages for a lift-type vertical axis wind turbines is its higher power coefficient ( C p ). However, the lift-type vertical axis wind turbines is not a self-starting turbi

Coherent structures are ubiquitous in unsteady flows. They can be regarded as certain kinds of spatial-temporal patterns that interact with the neighboring field. Although they play a key role in convection and mixing, there is no consensus on how to

Under different relative inflow angles, this paper studies the control mechanism of off-surface small structure which is referred as micro-cylinder. With varying positions, the effect of micro-cylinder on reducing the flow separation on the horizonta

Planted shelterbelts are widely used to reduce wind speed in order to control aeolian sediment transport. Both the morphology of each plant and the distribution of multiple plants are the key parameters to determine the wind reduction efficiency of s

The topographic parameters and propagation velocity of Aeolian sand ripples reflect complex erosion, transport, and deposition processes of sand on the land surface. In this study, three Nikon cameras located in the windward (0-1 m), middle (4.5-5.5
