CFD Simulation of Hydrodynamics in a Liquid-Liquid Extraction Column (6 months)

Join an innovative team at IFP Energies Nouvelles!
We are looking for a motivated and passionate student for a 6-month internship focused on numerical simulation applied to a key area of green chemistry and recycling.

Are you passionate about numerical challenges and advanced simulation tools? Do you want to contribute to innovative solutions in the field of bio-based chemistry and recycling? This internship is the perfect opportunity for you!

Context

With the rise of bio-based chemistry and the circular economy, liquid-liquid extraction has become an essential solution for separating molecules of interest. This process, particularly used for thermosensitive or non-volatile compounds, is an alternative to distillation or crystallization.

At IFP Energies Nouvelles (IFPEN), we develop advanced numerical tools to design efficient extraction columns. Through CFD (Computational Fluid Dynamics) simulations, we optimize processes while reducing costs and physical experiments.

Description

Integrated into a dynamic and innovative research environment at IFP Energies Nouvelles, you will actively participate in work on the simulation of the hydrodynamics of a liquid-liquid extraction column with perforated plates, using the ANSYS Fluent software.

Your missions will include:

• Literature review: Understanding the basics of liquid-liquid extraction and existing simulation tools.
• Familiarization with tools: Getting acquainted with existing CFD simulations.
• Analysis and development: Post-processing of results, parametric study (geometry and operating conditions).
• Optimization: Proposing and testing modifications to improve extraction performance, notably through the calculation of quantities such as the Peclet number.

Required profile

• We are looking for a curious and meticulous candidate with:
• Solid knowledge in fluid mechanics (ideally two-phase), CFD simulation, and chemical engineering.
• Skills in data analysis, synthesis, and drafting of technical documents.
• The ability to work in a team.

Additional information

- Duration : 6 months (starting between February and March 2026).
- Location : IFP Energies Nouvelles Rond-point de l'échangeur de Solaize, 69360 Solaize (20 km south of Lyon, shuttle available).
- Transport : public transportation / personal vehicle
- Compensation : approximately 1130€ gross/month
