| description | The invention discloses a discrete element fluid-solid coupling numerical simulation method and a discrete element fluid-solid coupling numerical simulation system based on a GPU matrix. The discreteelement fluid-solid coupling numerical simulation method comprises the steps of: establishing a pore network model; establishing a fluid unit migration model, wherein fluid units in pores are connected through pore throats among particle units, permeation of the fluid units obeys the Darcy law, the flow of the fluid units is determined by rock and soil mass properties, pore throat diameters and the like, and water pressure, temperature and density have a function relational expression; and exerting fluid-solid coupling effect, wherein pore water pressure acts on the particles, and the particlemovement changes the pore volume, so that a fluid-solid coupling effect is realized. According to the discrete element fluid-solid coupling numerical simulation method, dynamic simulation of a large-scale fluid-solid coupling |
