![]() ![]() Micro scale simulations are performed of flow through porous (pyrolyzing) thermal protection system (TPS) materials using the direct simulation Monte Carlo (DSMC) method. in Chemical Vapor Infiltration (CVI) or filter clogging simulations. They are easy-to-use tools for large-scale numerical simulations of mixed-mode gas flow, eg. Finally, the dimensionless friction factors related to Knudsen diffusion, binary diffusion and viscous flow have been found to be correlated between each other, regardless the flow direction or the type of fibrous media. Accordingly, this work proposes useful extensions of these known correlations towards lower values of porosity. porosity are in agreement with fibrous filters literature values, that are available for pore volume fractions above 55%. The reported tendencies of the mass transfer coefficients vs. An excellent agreement has been found for Darcian permeabilities and for Knudsen diffusivities, when taking the mean solid chord length as a characteristic length scale. pressure drop experiments and numerically with X-ray computerized micro-tomography (μ-CT), image processing and image-based computations. Permeation of gases in fibrous preforms of C/C composites has been studied with various degrees of infiltration, between 60% and 12% pore volume fraction, both experimentally with steady-state flow vs. Finally, diffusive tortuosities of a fibrous material are computed by applying the discussed numerical methods to 3D images of the actual microstructure obtained from X-ray computed micro-tomography. We discuss the upscaling of pore-resolved simulations to single species and multi-species volume-averaged models. We show that for particle methods, the surface representation significantly affects the accuracy of the simulation for high Knudsen numbers, but not for continuum conditions. These numerical methods include a finite-volume method for continuum conditions, a random walk method for all regimes from continuum to rarefied, and the direct simulation Monte Carlo method. In this work, we present numerical methods suitable for large scale simulations of diffusive transport through complex microstructures for the full range of Knudsen regimes. The data from these DNS are then used to close material’s macroscale transport models, which rely on effective material properties. Advances in X-ray micro-computed tomography (μ-CT) imaging provide the geometry of the material at the microscale (microstructure) thus enabling direct numerical simulation (DNS) of transport at the microscale. It is also within the ToS to simply ban an addon, but it's a pain getting the message out to all players that they cannot use the addon or any modified version of it.The diffusive tortuosity factor of a porous media quantifies the material’s resistance to diffusion, an important component of modeling flows in porous structures at the macroscale. It'll hopefully also introduce something to prevent honour farming GYs. I expect a number of devs have advocated bringing back raid queuing, its an easy fix and people clearly want to do it. They could remove part of the API that lets addons queue for BGs, but then its going to break other addons, so I doubt that will be popular. When there was only a few of these going it wasn't enough of a problem to deal with it, but now that it is popular and a hot topic on the forums, they're having to turn to it. ![]() I would be surprised if it was an actionable offence though. However, because we used to be able to queue with raids previously, this addon is adding functionality that was intentionality removed. If this hadn't existed previously, the addon would be merely adding new functionality to the game. In the distant past, it was possible to queue much larger groups, then Blizzard removed that and only allowed single-queuing, and eventually put the 5 person limit in.I think this is key to whether it is acceptable behaviour or not. ![]()
