Between September and December 2025, Martin Veit carried out a research visit to Forschungszentrum Jülich as part of his PhD work on gas-phase measurements. He was hosted by Prof Lukas Arnold and Dr Alex Belt, whose support enabled an intensive experimental campaign focused on advanced fire measurement techniques.

The main objective of the visit was to perform Particle Image Velocimetry (PIV) measurements in a reduced-scale compartment, allowing for a detailed investigation of flow dynamics in compartment fires. The experiments were designed to generate high-quality datasets that can be compared with alternative measurement techniques and numerical simulations, strengthening the experimental basis of Martin’s doctoral research.

Throughout the stay, Martin conducted a comprehensive series of tests that will form a core component of his PhD thesis. In addition, he presented his ongoing work at Forschungszentrum Jülich, highlighting high-fidelity velocity measurements at compartment openings and their relevance for improving the understanding and modelling of fire-driven flows.

The visit further reinforced collaboration between FRISSBE researchers and Forschungszentrum Jülich, contributing to the development of robust experimental methods in fire safety science.
