ABSTRACT: We consider a pressure (density) in a
square flume solid boundaries and no-slip format condition formulation are introduced
to investigate cavitation bubble for the two-dimensional lattice Boltz- mann
method (LBM). Using the coupling Carnahan-Starling equation of state (C-S EOS)
and exact difference method (EDM) based on modified Shan-Chen model, the whole
process of bubble collapse was observed complete and visual with equilibrium
distribution function and rebound format. This paper analyzes the bubble form
evolution, collapse time and dynamic character under the two dimensional press
fields.
