Fluid Dynamics Beyond the Continuum -- A Physical Perspective on Large Eddy Simulation
Max Okraschevski, Sven Hoffmann, Katharina Stichling +2
In this work, we will present a physically consistent theory to derive the governing equations of the Large Eddy Simulation (LES) framework based on first principles rather than th…
Implicit Molecular Stresses in Weakly-Compressible Particle-Based Discretization Methods for Fluid Flow
Max Okraschevski, Niklas Buerkle, Rainer Koch +1
Weakly-compressible particle-based discretization methods, utilized for the solution of the subsonic Navier-Stokes equation, are gaining increasing popularity in the fluid dynamics…
Towards DeepSpray: Using Convolutional Neural Network to post-process Shadowgraphy Images of Liquid Atomization
Geoffroy Chaussonnet, Christian Lieber, Yan Yikang +6
This technical report investigates the potential of Convolutional Neural Networks to post-process images from primary atomization. Three tasks are investigated. First, the detectio…
Influence of the ambient pressure on the liquid accumulation and on the primary spray in prefilming airblast atomization
Geoffroy Chaussonnet, Sebastian Gepperth, Simon Holz +2
The influence of the ambient pressure on the breakup process is investigated by means of PIV and shadowgraphy in the configuration of a planar prefilming airblast atomizer. The amb…
On the use of circulant matrices for the stability analysis of recent weakly compressible SPH methods
Geoffroy Chaussonnet, Rainer Koch, Hans-Joerg Bauer
In this study, a linear stability analysis is performed for different Weakly Compressible Smooth Particle Hydrodynamics (WCSPH) methods on a 1D periodic domain describing an incomp…
