Negative Pressure Tail of a Reflected Pressure Pulse: A Lattice Boltzmann Study
In this paper, a numerical pressure wave reflection experiment in a two-dimensional liquid is presented. The liquid is simulated by the pseudo-potential extension of the lattice-Boltzmann method. In our experiment a pressure pulse is produced by a point source and the resulting pressure wave is reflected back by a wettable rigid wall. Negative pressure tail can be observed at the vicinity of the wall/liquid interface.
