AI Technical Summary
Existing technologies are insufficient for efficiently evaluating the packing morphology and porosity of non-spherical proppants. Physical experiments are time-consuming, and numerical simulation methods fail to effectively account for proppant particles with complex shapes.
The surface of the proppant particles is decomposed into parametric surfaces, Lagrange points are randomly arranged and the interaction distance is defined. Based on the principle of interaction, the Lagrange points repel each other to reach equilibrium, the particle shape is determined, and the packing morphology and porosity of the particle group are calculated.
It enables efficient evaluation of complex particle packing morphology and porosity, freeing it from the limitations of spherical proppant shape and supporting the design of complex proppant shapes.
