In light of the ongoing climate and energy crisis, sustainable power generation is urgently needed. Inertial confinement fusion (ICF) is a promising alternative that uses lasers to ignite small, fuel-filled targets, triggering a fusion reaction. This all-weather technology produces no long-lived radioactive waste and poses fewer safety risks than nuclear fission. In 2022, ICF demonstrated its first net energy gain. However, there is still a long way to go before it can be commercialized.

Currently, diamond targets are used that are time- and cost- intensive while having a high rejection rate and a limited batch size. In contrast,microfluidic chips hold great promise for producing economical fusion targets. Together with the startup Focused Energy, we research on making microfluidically produced targets competitive and ensure they meet required standards.

Who hasn’t noticed strands of hair clumping together after a shower? The cause is a phenomenon called elastocapillarity. Surface tension from water drops exerts forces that deform flexible materials like fibers. Thus, hydrophilic fibers can get coiled inside droplets, a behavior also seen in nature. For example, spiders use micro-drops to enhance the elasticity of their webs. This principle may offer interesting applications in biomimetics. and microelectronics. Furthermore, this effect can be used in industry to produce micro-electronics. In our research, we investigate the fundamental dynamics of fiber-laden droplets.

Decarbonizing the chemical industry is a key challenge on the path to CO2 neutrality. For this reason, we are working in the BMBF-funded future cluster ETOS on the transformation of the chemical industry towards more climate-friendly lectrochemical technologies.

In this work, the wetting of abstract gauze structures is to be investigated using numerical simulation with OpenFOAM. In particular, the influence of different orifice geometries and wetting properties on the forming phase boundary and a possible bubble formation at too high differential pressures shall be investigated.
