Energy-group Wise Self-adaptive Refinement of Unstructured Mesh for Neutron Transport Simulation

Yuanzineng kexue jishu
In order to balance the accuracy and efficiency of neutron transport simulation, performing self-adaptive mesh refinement and domain decomposition parallelization for unstructured meshes are technologies that worth exploring.

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

Advanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Geometric feature-enhanced reconstruction and refinement of photogrammetric mesh models in man-made environments

GIScience & Remote Sensing
The automatic reconstruction of photogrammetric mesh models often suffers from issues such as erroneous adhesion of different planes, local distortions, and the loss of edge details.

3D finite element modelling optimization for deep tunnels with material nonlinearity

Underground Space, 2018
3D modeling of tunnels using a nonlinear ground model is still a time-consuming task because it usually requires a large number of incremental phases with iterative processes, to ensure accuracy while minimizing computational effort.

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

Advanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

Gas-kinetic scheme with space-time adaptive mesh refinement

Advances in Aerodynamics
The gas-kinetic scheme (GKS) is based on the mesoscopic gas-kinetic theory and can achieve a good balance between accuracy and robustness in a wide range of flows. In this study, a new GKS with space-time adaptive mesh refinement (STAMR-GKS) is developed

High-resolution numerical simulation of rotating detonation waves with parallel adaptive mesh refinement

Applications in Energy and Combustion Science
Simulations of rotating detonation engines are still dominated by solvers on uniform or statically refined meshes. Here, simulations of premixed rotating detonation waves are conducted using the block-structured adaptive mesh refinement (SAMR) technique.
