Main task was from the beginning to develop calculation methods for certain parts of a diaper machine where pulp fibres is transported by air. Later on absorbtion calculations where made. Where responsible for contacts with universities and consultants.
Project example:
Glue system modeling
During speed increases on the diaper machines the glue system was to slow (which led to a couple of products with less glue). Solved the problem by calculate an “ideal” speed curve for the glue pump. A simplified variant of that curve was implemented in these machines.
Fluff Pad Machine Design
A recurring task. Ofte performed together with a design engineer. After the design phase the machine had to be fine tuned in the factory. The tuning involved some flow measurements.
Absorption simulation in SAP/pulp mixtures
Achieve necessary material data for absorption simulation of a SAP/pulp mixture. Sensitivity analysis of material parameters.
Short description of absorption simulation: The fluid penetrates the porous stucture by diffusion. The SAP (Super Absorbent Polymers) capture the fluid and expand the structure. The structure often expand more than 3 times its initail thickness (volume).
Pressure drop analysis of non-newtoninan fluids through porous media
Analysis of permeability with a couple of blod types and test fluids through porous materials with different bulk density. When the flow speed was changed the permeability rank between the materials also was changed (because of different shear thinning in the blood).
-
Optimalisation of hammers in a pulp grinder. 2-dimensional CFD-analysis (sliding mesh)
-
Hydroentangling CFD analysis.
-
Transient fluff machine calculation to find sound generation place.
-
CFD-analysis of flow around glue nozzle.
-
Optimalisation of suction box.
-
Finite element analysis of towel paper to evaluate elasticity depending on embossing pattern.
Example of external contact:
ITWM, university in Kaiserslauten
Analysis of tissue micro structure. Permeability analysis of tissus by image analysis coupled with 2- or 3-dimensionar flow simulation of the same structure.
