Method for simulating flow of temporary plugging agent in hot dry rock complex fracture network

The invention relates to a method for simulating the flow of a temporary plugging agent in a hot dry rock complex fracture network. The method comprises the following steps: researching the migration process of the granular temporary plugging agent in the complex crack of the hot dry rock; building a complex fracture physical model and a CFD-DEM coupling model for simulating the transportation process of the granular temporary plugging agent in the hot dry rock complex fracture network; taking temporary plugging agent particles as a dispersed phase, and taking fluid as a continuous phase; considering the interaction between the particles and the fluid and the interaction between the particles; meanwhile, considering the influence of temperature change on relevant attributes such as particle deformation, aggregation and friction coefficient of the temporary plugging agent, so that bidirectional coupling calculation of a continuous phase and a particle phase is realized. The movement of the particles of the tem
