This article describes the implementation and validation of a nucleate boiling model in volume-of-fluid solver OpenFOAM. Emphasis is put on contact line evaporation, which can typically not be resolved by numerical grid, conjugate heat transfer between solid fluid. For validation, sucking interface problem growth spherical bubble have been simulated successfully. In order to validate transfer, from heated steel foil has calculated.
This publication lays the foundation for description of Multiscale Boiling Experiment, which was conducted within two measurement campaigns on International Space Station between 2019 and 2021. The experiment addresses fundamental questions about two-phase heat transfer during boiling processes. For this purpose, single or few subsequential bubbles are selectively ignited a heated substrate using short laser pulse. A detailed investigation phenomena is possible, as process temporally slowed...
The effective usage of renewable energy sources requires ways storage and delivery to balance demand availability divergences. Carbon-free chemical carriers are proposed solutions, converting clean electricity into stable media for storage, long-distance trade on-demand generation. Among them, hydrogen (H2) is noteworthy, being the subject significant investment research. Metal fuels, such as iron (Fe), represent another promising solution a supply, but establishing an interconnected...
As the urgency for decarbonization of economies around world is becoming more pressing, green energy carriers synthesized with renewable are emerging as tradable commodities connecting regions abundant to those high demand. Among various options, metals – especially iron have been identified by scientific community promising fuels due their volumetric densities. However, there persists a gap in comprehensive thermodynamic analyses despite growing interest. This study provides rigorous...
We consider the evaporation of volatile liquid droplets deposited on a heated substrate in pure saturated vapour environment. A mathematical model is developed that incorporates effects surface tension, evaporation, thermocapillarity, gravity, disjoining pressure, as well unsteady heat conduction solid substrate. The apparent contact line treated mathematically transition region between macroscopic droplet shape and adsorbed film Theoretical parametric studies are conducted to clarify...
Abstract The electric energy demand of data centers in Germany has grown rapidly from 10.5 TWh/a 2010 to 13.2 2017, an average 25% which are used fulfill the centers' cooling demand. In order increase its efficiency, TU Darmstadt applies a new concept next generation high‐performance computing center “Lichtenberg II.” Instead current air‐cooled servers with water‐cooled rear doors at 17‐24°C, will be equipped direct hot‐water for computer, supplying heat temperature 45°C. high‐temperature...
