Lattice group models (LGpM) are kinetic models on integer lattices derived from the automorphism group of the lattice. In the last decades it was too expensive to simulate large systems (100 1000 velocities in a 2D or 3D model), with complex physical two or three dimensional domains, on normal computers or clusters within an acceptable amount of time. That changed due to the fast growth of the ...

We present dye visualizations of the wake behind a flexible plate flow when its leading edge is forced into harmonic heave motion. We show that, when the forcing amplitude is sufficiently large, a reverse Bénard-von Kármán vortex street is formed in the wake, indicative of the production of positive thrust.

in the present paper, we shall attempt to make a contribution to approximate analytical evaluation of the harmonic decomposition of an arbitrary continuous function. the basic assumption is that the class of functions that we investigate here, except the verification of dirichlet's principles, is concurrently able to be expanded in taylor's representation, over a particular interval o...

This paper studies Karman vortex shedding and water-level fluctuation in the inverted siphon structure of Middle Route South-to-North Water Diversion Project (MR-SNWDP) China. Field investigations numerical simulations for outlet were performed to explore characteristics hazards vortex. Numerical results compared with measured data verify effectiveness reliability model. Based on model, it is f...
