Input and output data from simulations of 2D valves and 3D inflow-outflow model using particle methods

Input and output data of open-source softwares for computational fluid dynamics simulation involving fluid-structure interaction.

Data from two studies

1. Verifications of the weakly-compressible smoothed particle hydrodynamics (WCSPH) method, open-source code SPHinXsys, when applied to the flow of idealized 2D valve models.
2. Validations of inflow-outflow model in moving particle semi-implicit (MPS) method, open-source code PolyMPS.

Folders and Files

valve-2D.zip is the folder with data from the idealized models of vertical and curved 2D valves:

• Vertical valves with parameters provided in Gil et al., 2010
• Curved valves with parameters provided in Wick, 2014
• source files (.cpp): input data (physical and numerical parameters) for SPHinXsys
• text files: SPHinXsys (.dat) and Reference (.tsv) results
• python files (.py): Generates the graphics

inflow-outflow-3D.zip is the folder with data from the inflow-outflow model in MPS:

• Fluid physical properties of water
  • \(\rho=1000kg/m^3 , \,\, \nu=10^{-6}m/s^{-2}\)
• Pipes of length \(L=0.15m\):
  • circular section of diameter \(D=0.1m\).
  • square section of sides \(S=0.1m\).
• Constante pressure variation (\(\Delta P = 30 \,\, or \,\, 50 \,\, Pa\)) between inflow and outflow:
  • \(\frac{\partial p}{\partial x} = - \frac{\Delta P}{L}, \\ \Delta P = P_{outflow} - P_{inflow}\)

• Sinusoidal pressure variation (\(\Delta P =700Pa \,\, , \,\, T = 2.0s\)) between inflow and outflow
  • \(\frac{\partial p}{\partial x} = - \frac{\Delta P}{L} \sin \omega t \, \\ \omega = \frac{2\pi}{T} \\ Delta P = P_{outflow} - P_{inflow}\)
• input data (.json, .grid, .stl): physical properties, numerical parameters and geometries for PolyMPS can be found at https://github.com/rubensamarojr/polymps/tree/inOutflow/input
• text files (.txt): PolyMPS and OpenFOAM results
• python files (.py): Generates the graphics
