Purpose and goal
The unique methods and tools for simulation of spray painting, which were developed in earlier FFI and MERA project, have in this projects been extended to simulation of powder and externally charged wet paint, and support companies to develop and optimize their surface treatment to be more environmentally friendly, to be more energy efficient, to be more cost efficient, to give a higher product quality result
Results and expected effects
The project results show that it is possible to accurately simulate spray painting of a truck cab or a car in only a few hours on a standard computer. This is an extreme improvement compared to earlier approaches that require weeks of simulation time. Unique algorithms for coupled simulations of air flows, electrostatic fields and charged paint particles have made this possible. Several successful measurements campaigns have been performed on relevant industrial cases with very good results.
Approach and implementation
The project was divided into seven work packages. The first three focused on the modeling, simulation and optimization, and the remaining four concerned the measurements and validation, software demonstrator and exploitation, long term strategy of the area and project management.
