Workshop “Hydrogen in Heat” of the STROM project

Hydrogen is currently being discussed as one of the future energy sources in the energy transition. The question therefore arises in which areas hydrogen can be used sensibly and what challenges are associated with switching to the new energy source. As part of the STROM project, representatives from industry and research at the TUM Campus Garching dealt with this question on July 8, 2024. The…

Open day on October 3rd, 2024 at the Garching research campus

On Thursday, October 3rd, 2024, the Technical University of Munich invites you to an open day on the Garching research campus. You can look forward to an exciting program, because this year too, numerous institutions and companies warmly invite all visitors, students, employees and families to the research campus in Garching from 10:00 a.m. to 5:00 p.m. to find out about the diverse hands-on…

New publication on amplification of supersonic microjets by resonant inertial cavitation bubble pair

We reveal for the first time by experiments that within a narrow parameter regime, two cavitation bubbles with identical energy generated in antiphase develop a supersonic jet. High-resolution numerical simulation shows a mechanism for jet amplification based on toroidal shock wave and bubble necking interaction. The microjet reaches velocities in excess of 1000  m s−1. We demonstrate that…

New publication on beam shaping in laser-based powder bed melting of metals - A computational analysis of point-ring intensity profiles

Laser-based powder bed fusion (LPBF) is a manufacturing process that allows for creating materials with local variations in properties and alloys. One promising technique being researched is the shaping of the laser beam used in the process. Traditionally, a Gaussian laser beam profile is used, which has a high energy peak in the center and strong energy gradients. An alternative is the point-ring…

New paper “Investigations on particle emissions of large-bore engines powered by natural gas and hydrogen”

Hydrogen is becoming increasingly important as a future fuel in stationary applications and shipping. Hydrogen-powered engines are also an interesting subject for research because their emissions are, in principle, carbon-free. If particles are nevertheless detected in the exhaust gas, for example, these must originate from the combustion of lubricating oil, so that conclusions can be drawn about…

Recent publication from the Chair of Automotive Technology: Transfer of differential voltage and incremental capacity analysis from cell to vehicle level for electric vehicle battery health estimation

In the latest publication from the Chair of Automotive Technology, researchers investigated the transfer of Differential Voltage Analysis (DVA) and Incremental Capacity Analysis (ICA) from the cell level to the vehicle level. The goal is to estimate the State of Health (SOH) of the traction battery in electric vehicles. For this purpose, data from a VW ID.3 and a Tesla Model 3 were recorded during…

Munich Hydrogen Symposium 2024: Successful dialogue on hydrogen technologies

The recent Munich Hydrogen Symposium (MH2S) held on the TUM campus brought together experts, industry representatives and researchers from around the world to advance the field of hydrogen through shared knowledge, collaboration and innovation. The MH2S was a significant step towards establishing a dynamic international research hub for hydrogen technology.

New ENS publication on hydrogen production in Texas

As part of a collaboration with the University of Texas at Austin, hydrogen production in Texas with subsequent transport to Germany was analyzed. Current climate policy developments in the USA were taken into account.

Visit to the Institute of Sustainable Mobile Powertrains as part of the TUM H2 Network

Last week, the TUM.PtX and H2 Network had the opportunity to visit the Chair of Sustainable Mobile Drive Systems at the site in the west of Munich. Invited by Dr. Martin Härtl, the participants were able to gain exciting insights into the research activities and test facilities of the chair.
