The intrinsic physical relationship of vorticity between modes A and B in the three-dimensional wake transition is investigated.Direct numerical simulations for
Flower petals have not only diverse macroscopic morphologies but are rich in microscopic surface patterns, which are crucial to their biological functions. Both
The fluid-in-cell(FLIC)approach of Gentry et al.(1966)is extended to second-order accuracy in space and applied to solve the 2D shallow water equations with top
