IT for Engineering (it4e) GmbH software

IOTlab is the it4e product and service division for process data acquisition and control via the internet. IOTlab comprises modular hard- and software components which we can offer as cost-saving standard packages or compose individual configurations adjusted to special customer demands.  

The DNSlab simulation software is a tool for design and analysis of porous structures for technical applications, especially in the field of filtration and adsorption. The 3D models of the porous structures are generated or imported by DNSlab, e.g. from tomography data. By methods of image analysis, computational fluid dynamics (CFD) and by modeling of particle collisions (discrete element method, DEM), amongst others porosity, permeability, filtration efficiency, filter cake build-up and backwashing, adsorption loading and breakthrough curves can be determined for the porous structures.

For a 3D model of a porous medium, the pressure drop curve for a permeating Newtonian gas or liquid can be computed fully automatic. Mesh generation or adjusting boundary conditions is not necessary any more. After the dimensionless flow computation over a wide range of flow velocities has completed, the pressure drop for arbitrary Newtonian fluids can simply be determined by input of the density and the viscosity and the face velocity or the volume flow respectively mass flow and the inflow area.
