Description:
The dataset contains heat flows in periodic open-cell foam structures (Kelvin cell lattices)
for different strut-diameters, cell-diameters, thermal conductivities,
and gas flow velocities. The research objective is to establish relations
between the architecture and material of the periodic open-cell foam structure
and their heat transport characteristics. The data was extracted from
Computational Fluid Dynamics simulations.
This dataset contains the following files:

Explanation of variables:
- identifier (text): unique case identifier
- structure (categorical): type of structure
- dc (numerical, float): cell diameter of Kelvin cell in millimeter
- ds (numerical, float): strut diameter of Kelvin cell in millimeter
- epso (numerical, float): open porosity of the periodic structures; dimensionless
- SV (numerical, float): specific surface area of the periodic structure in square meter per meter cubed
- v (numerical, float): superficial fluid velocity at inlet in meter per second
- lambda (numerical, float): solid thermal conductivity in watt per meter and Kelvin
- S (numerical, float): absolute intensity of heat source for the quarter-pipe structure in watt
- T_max (numerical, float): maximum temperature in the solid in Kelvin
- T_mean (numerical, float): mean temperature in the solid in Kelvin
- F_SW (numerical, float): heat flow across the tube wall in watt
- F_SF (numerical, float): heat flow across the surface area of the structure to the fluid in watt
Methods, materials and software:
The Kelvin cell lattices were created with Autodesk Fusion 360 using the cell diameter
and the strut diameter of the underlying Kelvin cell as input parameters. Afterwards,
the Kelvin cell lattices were clipped to a cylinder representing the reactor tube.
The Computational Fluid Dynamics simulations were performed with OpenFOAM® v5.
The computational meshes for the fluid and solid phase were created with OpenFOAM®'s snappyHexMesh tool.
For the simulations, steady, laminar, incompressible flow of a Newtonian fluid (air) was assumed.
The temperature boundary conditions at the inlet and at the reactor tube wall were set to 500 K.
The fluid dynamic viscosity and the fluid thermal conductivity were updated based on the local
fluid temperature with the Sutherland and Eucken equation, respectively. The steady-state
heat flow across the tube wall was calculated from the simulation results with OpenFOAM®'s wallHeatFlux tool.
