Coupled Level-Set Lattice Boltzmann Method on Adaptive Cartesian Grids
Julian Vorspohl, Yuxing Peng, Matthias Meinke +2
A novel coupled level-set lattice Boltzmann method on adaptive Cartesian grids for simulating liquid-gas multiphase flows is presented. The approach addresses the inherent challeng…
The HydroGym Reinforcement Learning Platform for Fluid Dynamics
Christian Lagemann, Sajeda Mokbel, Miro Gondrum +18
Modeling and controlling fluids is critical across science and engineering. Effective flow control can increase lift, reduce drag, enhance mixing, and attenuate noise, potentially…
Comparative Analysis of the Flow in a Realistic Human Airway
Mario Rüttgers, Julian Vorspohl, Luca Mayolle +7
Accurate simulations of the flow in the human airway are essential for advancing diagnostic methods. Many existing computational studies rely on simplified geometries or turbulence…
Trailing-Edge Noise Reduction using Porous Treatment and Surrogate-based Global Optimization
Jan Rottmayer, Emre Özkaya, Sutharsan Satcunanathan +6
Broadband noise reduction is a significant problem in aerospace and industrial applications. Specifically, the noise generated from the trailing edge of an airfoil poses a challeng…
Impact of Engine Nacelle Flow on Buffet
Thomas Lürkens, Matthias Meinke, Wolfgang Schröder
The transonic flow around the OAT15A airfoil is computed at buffet conditions, i.e., freestream Mach number , chord-based freestream Reynolds number $Re_c = 2\cdo…
