Congratulations to Stéphane Stephane Zaleski from ∂'Alembert - SU & CNRS for being awarded the Medal for Mechanical and Computer Sciences by Académie des sciences. Our two-phase flow work would not have been possible without his pioneering contributions.

Interested in robust mixed modeling for Large Eddy Simulation? A new way to combine structural and functional models based on the local sub-grid activity is suggested here: doi.org/10.3390/fluids…

Paul Dirac's Ph.D thesis was not typed. It was handwritten and submitted in 1926. The title of the thesis was simply "Quantum Mechanics". Dirac is one of the founding fathers of Quantum Mechanics. ✍️

Generation of synthetic turbulence has been an active field of research for more than two decades. If you want to know how to generate a signal with a prescribed length scale and, in addition, a pre-specified probability density distribution: doi.org/10.1007/s10494….

Congratulations to our student Mr. Herbert for receiving the MBDA study award from DGLR for his Bachelor thesis „Comparison of Bunsen flame topology from experiment and DNS“.

Can we estimate 3D flame surface area or wrinkling from 2D measurements? A remarkable, surprisingly simple formulation is provided in our recent paper in Flow, Turbulence and Combustion: doi.org/10.1007/s10494…

Our recent article doi.org/10.1007/s10494… presents a VOF-based Eulerian-Lagrangian framework for Large Eddy Simulation of complex industry-scale sprays such as the non-evaporating ECN Spray A (see image). The results demonstrate the vital importance of sub-grid scale modeling.

Combining CFD simulations and machine learning, we refined droplet stacking in inkjet 3D printing, achieving an 85° stacking angle to enhance electrical performance. Discover the implications for high-frequency electronics: doi.org/10.1007/s00170…

Large Eddy Simulation (LES) of a full aircraft! Mesh Count: 1 Billion cells - The mesh was generated in 28 minutes on 512 cores, and the solve completes in 30 hours on 40 L40 GPUs. This simulation was part of the High Lift Prediction Workshop in August 2024. Source: Ansys

Using multiphase DNS, this new study explores how viscosity and surface tension differences in colliding droplets affect mixing efficiency and quality in bioprinting. These findings could help optimize printing techniques. Read more at: DOI.org/10.1007/s10494…

How to make sure that data-driven subgrid-scale models obey the proper asymptotic near-wall scaling without doing any computationally expensive a-posteriori channel flow simulations for training? Our solution using genetic algorithms: doi.org/10.1063/5.0260… #iCFD4NS BMFTR

Water injection is effective to reduce emissions & fuel consumption in ICEs. However, physical aspects of injecting water gasoline emulsions are not well understood. The SMD shows a weak non-linear behavior with increasing water content up to 50%. more at doi.org/10.1615/Atomiz…

In our @BMFTR_Bund funded project #iCFD4NS we evaluate the performance of advanced mixed LES models for polydisperse two-phase flows. Combining functional & structural models improves flow statistics, such as the gas volume distribution. #OpenAccess paper: doi.org/10.1016/j.ijmu…

How do water-in-gasoline emulsions help improve combustion? 🚗🔥 We combine experiments (a) and DNS (b) to uncover how emulsification works and how droplet sizes evolve. Read more: doi.org/10.1007/s42757… #CFD #DNS #Emulsions #Combustion #EnergyResearch
