In transportation networks, such as pipeline networks for transporting natural gas, it is often impractical to send across amounts of flow below a certain threshold. Such lower threshold is referred as the minimum-lot size. The network flow is semi-continuous when a network has minimum-lot sizes...
A Fast, Highly Accurate Means of Modeling Transient Flow in Gas Pipeline Systems by Variational Methods 来自 dx.doi.org 喜欢 0 阅读量: 80 作者:HH Rachford,T Dupont 摘要: The cost-effective design of real pipeline systems must consider thetransient response induced by equipment failure and sales...
The trifluoromethyl anion rapidly decomposes into difluorocarbene (:CF2) and fluorine ion, limiting its applicability in synthesis. Here, the authors report a strategy to generate and use the short-lived CF3- intermediate from stable CF3H gas via fast biphasic mixing in precisely customized flow...
From these predicted parameters, one can infer the health and serviceability requirements of the engine. 3.: We showed the importance of self-adaptive weights (given the fast transient dynamics) in the accuracy and faster convergence of results for PINNs for the present study. 4.: The engine ...
Preferential flow (also known as nonuniform flow or nonequilibrium flow) refers to the phenomena where fluid, gas, and/or solutes move through preferred pathways in a porous medium, thereby bypassing large portions of a porous system (Fluhler et al., 1996; ...
Setting gas flow control element modulation involves altering degree of modulation depending on integral wrt. time of control signal produced manually or b... The method involves altering the degree of modulation (M) of the control element (2) depending on the integral of a control signal (S)...
How fast and how far a lava flow can travel from the vent depends on its viscosity (itself determined by temperature, chemical composition, gas content, and crystallinity), eruption rate, and ground slope. Mafic lavas (e.g., basaltic lavas erupted from Hawaiian volcanoes) have low viscosity ...
Rapid response thermocouples differ from regular thermocouples as they must have a fast response speed, good gas-tightness, sufficient physical strength to cope with the impact of high-speed gas, and minimal effect on the original gas flow state.In temperature sensors with rapid response ...
These free vortices feel magnus force under the applied current and hence can move with very high velocities at large currents3. While the presence of ultra-fast moving vortices and its possible connection with phase slip lines (which are 2D analog of phase slip centers) has been demonstrated ...
