the meaning of Vitruvius' text statements concerning siphon operation, albeit in prescientific terminology, can be interpreted in light of the computed physical behaviour of the system.Analysis results indicate that impulsive siphon start-up is characterized by fluid column oscillations in all siphon bran...
Hence, although the meaning of Chi is very broad in classical Feng-shui sense, it may have something to do with the air and/or water flow within the flat, which is relatively easier to measure and simulate by computational fluid dynamics (CFD). In this paper, techniques in computational ...
The end of 2021 and beginning of 2022 saw the two largest commercial computational fluid dynamics (CFD) tool vendors, Ansys and Siemens, both launch versions of their flagship CFD tools with support for GPU acceleration. This fact alone is enough proof to show the new age of CFD has arrived...
If the Reynolds Number is small, then the flow will be laminar, meaning that the flow progresses in layers of the fluid with no € 8 macroscopic mixing of the layers. If the Reynolds Number is large then the flow will be turbulent, meaning there will be a mixing of flow layers and ...
Hence, models generally comprise the decoder-type structure [55, 74], meaning that the number of nodes gradually increases towards the output layer. This is especially the case for high-dimensional inverse problems such as super-resolution reconstruction of fluid flows. This leads to the number ...
The value of the computational fluid dynamics simulation is particularly driven by making the invisible flow structures visible31,32,33,34,35,36,37. In addition, we can obtain quantitative information of experimentally inaccessible quantities such as force distribution38, energy39, the streamlines, fl...

Density can vary concerning pressure, although it is assumed that the fluid is only weakly compressible, meaning that the Mach number is less than about 0.3. The k-ε equations are derived considering the flow has a high enough Reynolds number (critical Re = 2000). If this assumption is ...

Computational fluid dynamics (CFD) is a tool for modelling and simulating processes in many industries. It is usually used as a choice to solve problem involving flow of fluids, heat transfer, mass transfer and chemical reaction. Moreover, it has also found application in the optimization of pr...
