DEM simulation of impact force exerted by granular flow on rigid structures
Avalanche DEM Granular flow Impact force
2015/7/1
The paper presents a DEM model for simulating dry granular avalanche down an incline. Flow pattern and impact forces on rigid obstacles are considered. Results of the simulations are compared with exp...
Estimating the impact force generated by granular flow on a rigid obstruction
Debris flow Fluid dynamics Granular flow Impact force Slope failure
2015/7/1
Flowing sediments such as debris and liquefied soils could exert a tremendous amount of force as they impact objects along their paths. The total impact force generally varies with slope angle, veloci...
Investigation of Optical Flow Techniques for Extracting Non-Rigid Sea Surface Currents
Non-Rigid Sea surface currents Sea surface temperature Eddies Optical flow Smoothness
2014/12/1
This paper is about performance evaluation of two optical flow (OF) methods for extracting sea surface curved motions like eddies. By incorporating a simple matrix and its rotation in programming proc...
