Desired outcome

BIC is looking for advanced computer simulations that can accurately model how ink flows in a ballpoint pen during writing.

The writing performance of a ballpoint pen depends on the interaction between the ink, the ball and ball socket, and the paper. Fluid dynamic numerical simulations could help determine quantitatively on the one hand the magnitude of certain key parameters such as the ink viscosity, surface roughness, shear rate, stress & strain distribution etc and on the other their influence on ink flow and consumption.

The group has extensive empirical knowledge of the parameters affecting writing but has never used numerical simulations to further enhance it. A quantitative analysis of the influence of a system parameter on writing would help us pinpoint those that have to be adjusted to meet the expected product performance.
