Simulate absolute permeability on CT scans of different materials using the Transport Phenomena Simulation Module for VGSTUDIO MAX.
Permeability is the ability of a medium to allow a fluid to flow through.
The Transport Phenomena Simulation Module for VGSTUDIO MAX:
Permeability simulations are based on the following assumptions regarding the viscous flow:
In experiment mode, the software performs a virtual experiment on the CT data of a structure, simulating the flow of a fluid through the structure from an inlet plane towards an outlet plane parallel to each other. Perpendicular to the inlet and outlet plane, sealed or embedded boundary conditions can be defined. A pressure difference or total flow rate can be specified as driving quantities for the flow.
The results are provided as 2D and 3D visualizations of the velocity field as well as the pressure distribution. Flow directions can be visualized by streamlines in 2D and 3D:
The following additional results are provided in a table view:
The following results can be viewed as curve plots along the flow direction:
In tensor mode, the software calculates the intrinsic effective tensor-valued permeability. The calculation of the permeability tensor can be done on the whole structure or for increments of the structure by means of an integration mesh.
As a result for the absolute permeability, the software provides you the permeability tensor as 2D and 3D visualizations.
In addition to the tensors' eigenvalues and eigenvectors, the components of the absolute permeability tensor with respect to the simulation coordinate system are provided in a table view.
