In order to effectively characterize complex fracture network,a dual-porosity fracture network numerical simulation model is presented based on the seepage law in studied 3D region. Different fracture patterns are simulated using the model,the effect laws of the fracture patterns on the productivity of...
simulation optimization was carried out on design of the SCR reactor's inlet flue duct and guide vanes,based on which optimized flow field design obtained.Results show that the optimized design may help to raise the velocity uniformity at both the ammonia-injection grid(AIG) section and the ...
A simplified online solution for simulation-based optimization of earthmoving operations Daily field management of earthmoving operations requires quick and regular decisions for allocating available equipment to different jobs on a project. A general foremans day starts with matching several activities with...
The presented formulations are in the form of optimization problems and are called mathematical programming problems (mathematical programmes or mathematical programs, in short) in the field of operations research, which basically means that they are of the form minimizeF(x)subject tox∈S with a ...
Toward Accurate Simulation of Shockwave-Turbulence Interaction on Unstructured Meshes: A Coupling of High-Order FR and LAD Schemes A high-order flux reconstruction (FR) scheme on unstructured hexahedral grids is coupled with the localized artificial diffusivity (LAD) scheme for aiming at accurate simul...

(CFD).Flow field analysis of the simulation results showed that there were strong swirling and narrow flow channel in the flow field of prototype air-assisted duct.It also resulted in large CV in exterior free flow field.In response to these shortcomings,two kinds of improvement designs were ...
Variable-resolution models have been used in high-frequency electronics (including antenna engineering) for more than a decade to accelerate simulation-driven design processes78,87. Usually, two levels of models are used, often named coarse (also, low-fidelity) and fine (also, high-fidelity). Th...

It uses delocalized coordinates by default both for molecules and periodic systems. The molecular part is based mainly on the work by Marcel Swart 4. Cartesian coordinates are used in the presence of an external electric field and/or frozen atom constraints. The Quasi-Newton (QN) optimizer ...
