Methodological Approach for Particle Transport: Analyzing Influential Factors and Comparing Simulation Software

ABSTRACT Recent research shows the relevance of particle flow studies for particles smaller than 10 µm, especially in industrial contexts. Understanding behavior, deposition, and acting forces is essential for realistic particle‐transport simulations. This study analyzes these forces using as an example a venting tube from automotive headlights. Due to its simple geometry, the component is suitable for investigating particle‐laden flow and its implementation has been examined across different simulation frameworks. Furthermore, a transfer function was derived to quantify filtering efficiency and support methodological use in practice. All results serve as the basis for developing an appropriate simulation model and for creating a methodological approach representing particle transport.
