When an obstacle closes to a wall, the boundary layer on the wall and flow around the obstacle interact and form a complex flow field. The resulting flow is highly mixed and turbulent. Turbulence models are not modified to handle such a flow field...

In this work, we prepared few-layer graphene nanosheets in high yields by burning magnesium metal in dry ice and characterized by transmission electron microscopy, scanning electron microscopy, Raman spectroscopy, Fourier Transform...

In the simulation of wave propagation phenomenon truncating the grid will lead to unacceptable reflection artifacts from boundary. One remedy is to extend simulation region by Perfectly Matched Layers (PML) that contains a special absorbing medium...
