Fluid Dynamic Numerical Simulation Of A Ballpoint Pen Writing System
338 2024. 6. 11.
Summary
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.
Stage of Development
Description
Must Haves:
- Fluid dynamic numerical simulation of the ballpoint pen tip system (ball-tip-ink)able to take
into consideration certain key parameters such as the ink viscosity, surface roughness, shear
rate, stress & strain distribution etc, and their influence on ink flow and consumption. - Good agreement between numerical and experimental results
- Ability to identify key properties controlling the writing process
- Possibility to modify the system parameters (e.g., ink viscosity, ball roughness, etc.) to
determine the best possible configuration
Solution Requirements:
- Technology Readiness Level: Minimum 5 (technology has been validated in a relevant
environment, often through testing of components or subsystems in simulated operational
environments) - Any geographical area
- Any IP status is applicable
