Design of thermodynamic cycles and sizing of related equipment

About NEEXT

NEEXT is a young start-up located in Belfort and supported by FRANCE 2030 that ensures the industrial development of a main innovation based on new patented working fluids known as 'reactive fluids'. These promise to significantly improve the performance of thermodynamic cycles, particularly those related to heat-to-electricity conversion and heat pumps.

Context

NEEXT designs thermodynamic cycles using reactive fluids as working fluids. Those fluids patented by CNRS add a chemical dimension to the thermodynamic principles enabling a significant yield gain but increasing the complexity of the cycle. Since this is a recent innovation, it still requires a modelling effort to design and optimize both cycles and equipment. The upcoming activities are therefore focused on modelling and sizing processes and equipment.

Topics and missions of the internship

• Establish consistent and comprehensive design rules for the main cycle components (pumps, valves, pipes, heat exchangers, turbines, compressors).
• Develop tools for sizing and modeling the main components (ideally using Python scripts).
• Conduct conceptual studies for Neext's customers.
• Contribute to defining prototypes aimed at demonstrating industrial feasibility.

Your profile

• Agility, ability to adapt in a changing environment.
• Curiosity, proactive mindset and ability to make suggestions.
• Communication, ability to address blocking points and seek information within the team.
• Autonomy, capacity to propose action plans to ensure successful completion of assigned tasks.
• Knowledge of thermal engineering, fluid mechanics, and thermodynamics.
• Knowledge of and interest in programming.
• Operational proficiency in English.

Practical information

• Location: Belfort, France
• Start date and duration: starting February/March 2027 for 6 months
• Salary: we have cookies sometime (to be discuss, we pay all our interships)
• Possibility of employment at the end of the internship.
