Graphene boasts advantages such as high specific surface area, excellent electrical properties, and high tunability, making it highly promising for hydrogen storage applications. Compared to monolayer graphene, bilayer graphene exhibits a more easily controllable bandgap, showcasing its potential for hydrogen storage. Additionally, to further enhance the hydrogen adsorption capability of graphene-based substrates, doping methods are commonly employed to adjust their electrical properties. This study proposes a model for hydrogen adsorption on bilayer graphene to investigate its hydrogen storage capacity. Specifically, density functional theory (DFT) computational methods are utilized to study the adsorption of single and multiple hydrogen molecules on monolayer and bilayer graphene, with or without doping with gallium atoms. Furthermore, the underlying reasons for the enhanced hydrogen adsorption in gallium-doped bilayer graphene are systematically analyzed and elucidated. The research findings indicate that pristine graphene exhibits relatively low sensitivity to hydrogen gas, with adsorption energies of only −0.078 and −0.096 eV for monolayer graphene (MG) and bilayer graphene (BG), respectively. However, upon doping gallium atoms into MG and BG, the adsorption energy significantly increases by approximately 30.8 % and 54.1 %.

A numerical solver for non-Newtonian two-phase flow capable of describing granular flows on complex terrains has been implemented.

The predictions regarding depth-time curves at several critical probes and final deposition profiles demonstrate superior accuracy compared to previous forecasts based on depth-averaged models. Additionally, an analysis of the evolution of impact forces exerted by granular flows on obstacles reveals that shoulder obstacles can significantly mitigate impact forces within primary flow regions.

The rod-like particles were modeled by multi-sphere method. To assess the mixing performance, both qualitative and quantitative measures were employed, including visual examination of fluidized beds and evaluating subdomain-based mixing index. It was shown that the continuous injection of single bubbles can significantly improve mixing compared with the case of no bubble injection. Furthermore, when the number of rod-like particles increases, the continuous injection of single bubbles is an effective technique for improving mixing. In processes where gas utilization is critical and cost optimization is paramount, continuous injection of bubbles can reduce the gas volume required.

The results show that the fan-shaped ribs can effectively reduce particle deposition and exhibit greater deposition inhibition with increasing rib height. The channel constriction induced by the rib structure promotes the radial diffusion of particles in the downstream, and at the same time significantly enhances the radial component of the particle flow, which is improved by 5.76 %, 7.98 %, and 10.86 %, respectively. In addition, recursive analysis revealed that the incorporation of fan-shaped ribs shifted the particle flow from a homogeneous, periodic mode to a more abrupt diffusion mode, which contributed to the improvement of particle dispersion.
