Coal contains a large number of fractures, whose characteristics are difficult to describe in detail, while their spatial distribution patterns may follow some macroscopic statistical laws. In this paper, several fracture geometric parameters (FGPs) were used fracture, and the coal seam was represented by two-dimensional stochastic network (SFN) which generated processed through series methods MATLAB. Then, SFN image able be imported into COMSOL Multiphysics converted computational domain...

The understanding of the rock-cutter interaction is essential for efficient rock cutting/drilling performed with polycrystalline diamond compact (PDC) cutters in petroleum engineering and gas exploration. Finite element modeling cutting process still remains a challenge due to complex material properties rock, fracture chip formation phenomena large force oscillations during dominant brittle mode.

Abstract Polysaccharide-based aerogels show great potential in heat absorption, but it lacks comprehensive evaluation system for their endothermic properties. To fully assess properties, konjac glucomannan (KGM)/starch aerogel was used and its absorption performance (HAP) investigated. It found that the ability of samples attributed to thermal collapse at high temperature. The composition, structure, size mass would have effect on HAP. cellulose acetate (CA) showed better HAP than KGM/starch...
