My researches involve fluid mechanics and more precisely:

• theoretical stability analysis
• direct numerical simulations of two-phase flows

In particular, during my PhD thesis, I was interested in numerical simulation of compressible two-phase flows with evaporation in ARCHER code.

During my postdoc, I studied the stability of a Newtonian ferrofluid jet under a magnetic field.

Currently, my researches are divided into several projects:

• Supervision of Qi Fang PhD thesis on the development of Magneto-Hydro-Dynamics in ARCHER code allowing the numerical simulation of liquid metal batteries.
• Theoretical stability analysis of a gas torus in a liquid.
• Continuation of the study of ferrofluid jets with
  • an experimental study (Antoine Bouchet internship) and the consideration, in the theory, of thermocapillary effects

                    R. Canu, A. Bouchet, M.-C. Renoult. New experiments and theory on ferrofluid cylinder in an azimuthal magnetic field.

• • a weakly nonlinear theoretical stability analysis
• Project in progress with LOMC laboratory about theoretical and numerical studies of ferrofluid seals.
• Involvement in the IRP MOLIMBA project led by Marie-Charlotte Renoult and in partnership with Jeonbuk university in South Korea, LOMC laboratory in Le Havre and LISN laboratory in Paris-Saclay (from 2025)
  • a weakly nonlinear analysis of “metal pad roll" instability in liquid metal batteries
• Involvement in the ANR AIRDROP project led by Dominique Legendre from IMFT laboratory in Toulouse (from 2025)
  • supervision of a postdoctoral researcher on a theoretical stability analysis of a liquid column dropped by an airtanker aircraft in the context of fire fighting.

A stability analysis of a ferrofluid jet under a magnetic field of general shape was realised. Several effects were considered :

• ferrofluid viscosity
• magnetic field sources

R. Canu, M.-C. Renoult. Linear stability analysis of a Newtonian ferrofluid cylinder under a magnetic field.

• surrounding fluid

R. Canu, M.-C. Renoult. Linear stability analysis of a Newtonian ferrofluid cylinder surrounded by a Newtonian fluid.

• non-linearities

R. Canu, M.-C. Renoult. Analyse faiblement non-linéaire de stabilité d’un cylindre de ferrofluide.

During my PhD thesis in the numerical simulation field, my researches mainly focused on atomization process. They were divided into three points:
