You can find below few examples of simulation results, that I have obtained using various scripts or codes, namely COMSOL, my own version of the SPH code SPHYSICS, and SIF².
- Landslides generated waves
- The experimental free surface (top) is in good agreement with my SPH simulation, performed with SPHYSICS (bottom).
- Simulation (COMSOL) of a rotating flow in an ellipsoid
- Iso-velocity 13% during 86 rotations (equatorial axes ratio b/a=0.72, polar axis c=(a+b)/2, Ekman E=0.002).
After the spin-up, the rotation axis is tilted by the tidal instability : this is the spinover mode.
- Kinematic VKS dynamo
- The velocity field of Gissinger (2009) provides a benchmark dynamo case, which allows to validate COMSOL.
- Sloshing tank (COMSOL)
- Diphasic moving mesh (ALE) simulations
- Sloshing tank probe
- Comparison of case G (fig. 26a) of Wu et al. (1998), solid black line, with SIF² (red dashed line) and COMSOL (blue dotted line)
- Interaction between tides & precession : a 1st step.
- A sphere filled with liquid is deformed by 2 rollers (in gray) into an ellipsoid and set in rotation (motor in black). The whole setup is then tilted and fixed on a rotating table.
This setup has been studied theoretically & numerically
- Oenodynamics (COMSOL simulation)
- Flow in the frame moving with the (orbiting) glass.
- Thermal convection (COMSOL simulation) : case 0 of the benchmark of Christensen et al. (2001).
- In the rotating frame, cylindrical radial velocity between -15.6 & 12.7 (Christensen et al. (2001) for details).
The Busse columns (above) is a base flow able to drive a dynamo.
- SPH simulation
- Motion of a rolling half-full Beer Can as it rolls down an incline.
- Impact of a buoyant sphere in a 2D water box
- No-slip boundary conditions & no surface tension.
A very rough simulation which shows the abilities of the numerical code.
- MHD experiment IMAGINE (with liquid metal)
- The induced magnetic field of the elliptical instability is studied with this setup.
