The DECHEMA/VDI Heat and Mass Transfer Section Annual Meeting 2025 at the University of Stuttgart was an excellent opportunity for the SynTrac team to present new results and showcase its interdisciplinary collaboration between sub-projects.

Abhishek Borad from the University of Stuttgart and Marit Blanke from Technische Universität Braunschweig, both sub-project B01: Functional integration and preservability of propulsors waste heat recovery, and Myles Zabel (University of Stuttgart) working on sub-project A02: Simulation of aircraft flow losses presented a joint poster titled: “A Potential Analysis of the Utilization of the Bypass Duct for Heat Transfer in Highly Integrated More-Electric Turbofans”

Together Abishek, Marit and Myles are working on optimizing waste heat recovery in highly integrated more-electric turbofan engines by utilizing structured surfaces in the bypass duct. Their research investigates how these structures enhance heat transfer while minimizing pressure loss and fouling due to particle deposition. Through numerical simulations and experiments, they analyze different geometries of ribs, dimples, pins, and bumps to identify optimal designs for improved thermal performance.

Before the poster session, there was a short poster pitch on the first day, where each presenter introduced their research in a concise format. The session provided a great opportunity for discussions, bringing together PhD students, professors, and industry experts to exchange ideas and provide valuable feedback.

Several lectures and discussions at the event explored topics relevant to SynTrac research, such as textured surfaces for enhanced heat transfer and fouling of structures surfaces. This further emphasized the importance of surface optimization for heat transfer applications, reinforcing the relevance of our work in waste heat recovery and particle deposition.
