Below are some illustrations of my research. The postprocessing mainly involves Python scripts, Paraview and the Matplotlib library.

landing gear aero-acoustics simulations
Flow simulation around the landing gear using the ProLB software. The isosurface of the Q-criterion visualizes vortices detaching from the landing gear walls, while a slice of the dilatation field highlights the locations of acoustic sources.

Clapeyron diagram FC70 gas

Reduced pressure-volume plot near the critical point of FC70 gas, computed using the Peng-Robinson equation of state. A small region where the fundamental derivative of gas, \(\Gamma\), is negative indicates the potential for non-classical shock dynamics. The compressibility factor, \(Z\), shown in shades of green, illustrates deviations from ideal gas behavior.

linear cascade of OGV
Simulation of a linear cascade of outlet guide vanes (OGVs). Various OGV geometries, including serrated and wavy designs, were analyzed to reduce acoustic noise emissions while maintaining the aerodynamic performance of the reference OGV.
viscous fingering
Viscous fingering, or the Saffman-Taylor instability, arises when one fluid displaces a more viscous fluid. Starting from a planar interface, fingers develop in the unstable configuration over time. In this case, the fluids consist of two species that can mix. The instability becomes more complex when three or more species are involved, leading to intricate finger patterns.
ECL 5 UHBR simulation Q criterion
ProLB simulation of the ECL5 open test case. ECL5 experimental bench, developed at LMFA, is representative of future ultra-high bypass ratio fan concepts.
roofline of a GPU LBM application
GPU roofline analysis of the compressible LBM code CoLaB for single- and double-precision floating-point operations. Colored lines represent the measured performance limits due to hierarchical memory caches.
vortex through a mesh transition
A vortex crossing a mesh transition with low acoustic noise emission. Multiple concentric pressure waves, originating from the initial conditions, are also visible.
Taylor-Green vortex Q criterion at Mach number 1
The Taylor-Green vortex (TVG) flow is a standard test case for studing the transition from laminar to turbulent flow in a decaying regime. It is also a popular benchmark to evaluate the accuracy of numerical schemes. Here, we simulate a compressible TGV at Mach 1. The initial state consists of eight vortices, which decay over time within a periodic cubic box. The interaction of multiple shock waves makes this configuration particularly challenging.
