Project

Reducing droplet impact on process surface

Location

ROCKWOOL products are produced by mixing stone wool fibers with glue in droplet form in a process chamber. The droplets are introduced near the rotating surface that spins the fibers, to facilitate an even coverage on the final product. However, the proximity to the spinning surface does pose a risk to the process, since the droplets negatively impact the spinning process if they get in contact with the spinning surface.

The goal of the project is to analyse the turbulent flow and the droplet trajectories near the spinning surface and, based on an analysis of the flows, investigate measures to reduce the droplet / surface impact probability.

The project tasks are as follows:
  1. Build a CFD model of the spinning wheel with a particle model to account for the droplets and fibers.
  2. 2) Analyse the current design to identify mechanisms for droplet / surface impacts.
  3. Design and test changes to the process to reduce the droplet / surface impact probability.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
