Creating innovative solutions via simulation

Filtration mesh and filtration solutions from GKD need to meet customer requirements exactly and provide efficient benefits. We achieve this using extensive simulations that are as close to the application and as conclusive as possible.

There are two material simulation tools we use for this: GeoDict® software, specially developed for porous structures, and the OpenFOAM simulation library. This is used primarily at universities and research institutes.

It is also thanks to our simulation expertise that we are market leaders in the development of new products – as an innovative and solution-oriented partner to industry.

We can create single- and multilayer as well as pleated filtration meshes virtually and combine them with a nonwoven, a foam, or other filter media depending on the application.

To ensure that the model is as close to reality as possible, we incorporate existing filtration meshes into the simulation environment by means of a computer tomography/CT scan. This allows us to precisely analyze the pore geometry of the filter medium even before the actual calculation.

From the simple pressure drop calculation of a wire mesh to the consideration of turbulent, compressible, and/or non-Newtonian flows to the analysis of entire filter systems: We can reliably predict the largest pore or the pore size distribution and porosity of a filtration mesh or mesh package. In the same way, we can calculate complex problems – for example, the treatment of multiphase flows, the interaction of fluid-solid systems (FSI), or heat transfer on woven structures.

Structural mechanics calculations on metal meshes or components using the finite element method (FEM) complete our portfolio.

With our simulation results, flow processes and their causes can be precisely observed and evaluated. Our development engineers use this as a basis for individually optimizing flow control according to customer requirements and application scenarios. In doing so, they pay particular attention to optimizing the flow rate of filter packages, reducing pressure drop, and identifying inefficiently used filter areas. Filtration efficiency as well as degradation behavior when using the filter medium in abrasive media can be determined just as precisely.
