Review: EVT at the ASME Summer Heat Transfer Conference (SHTC25) in Colorado
From July 7 to 10, 2025, Dipl.-Ing. Montadhar Guesmi and Dipl.-Ing. Johannes Manthey took part in the renowned ASME Summer Heat Transfer Conference (SHTC25) in Westminster, Colorado, USA. The focus was on international exchange on current developments in the field of heat transfer.

Both scientists presented key results of their research as part of the BMBF project H2Giga/Sinewave . The aim of the project is to investigate the cooling circuit of PEM electrolysers in more detail - in particular the formation of gas bubbles as a result of supersaturation and their influence on heat transfer and the flow pattern in the system.
Mr. Manthey presented his work on "Bubble Evolution in the Cooling Circuit of the PEM Electrolysis", in which he analyzed the formation and dynamics of gas bubbles in the cooling circuit and showed their effects on the thermohydraulic efficiency.

Mr. Guesmi gave a lecture entitled "Water-Oxygen Two-Phase Flow in the Plate and Frame Heat Exchanger: Flow Behavior and Thermal Performance Study". He shed light on the flow behavior and heat transfer mechanisms in two-phase flows in plate heat exchangers, as used in PEM electrolysis.
In addition to exciting presentations and discussions with international colleagues, the conference also offered the opportunity to visit the National Renewable Energy Laboratory (NREL). There, participants were given exclusive insights into various test stands and ongoing research projects in the field of sustainable energy technologies.
The trip was rounded off with a private hike up Mount Elbert, the highest peak in the Rocky Mountains - an impressive end to a successful conference visit.

The two return to Dresden with new impulses, exciting contacts and fresh motivation - inspired by the international research community and the unique impressions on site.
