Engineering solutions for the 21st century's increasingly complex challenges


In the last 30 years there has been an extraordinary increase in simulation and modeling tools, used by design engineers, decision makers and public services.

Research in mechanics and process engineering has provided a significant contribution to progress in these areas.

Today's scientific and technological challenges arise from new issues: sustainable development, alternative resource management, green technologies, environmental impact, risk management, health care...

 

The aim of Tec 21 Laboratory of Excellence is that our research contributes to finding engineering solutions for today’s increasingly complex challenges through


  • gathering new knowledge and understanding, developing new concepts and methods, and improving measurement as well as simulation capabilities...
  • giving rise to educational multidisciplinary development programs providing practical experience. 
  • working towards solutions with direct industrial and environmental applications.

Undulations, waves, drops: from the virtual to the real

When a high speed gas flow impacts upon a liquid, we witness the formation of undulations, waves and droplet. Atomisation phenomena, commonly observed at the crests of waves, are a key principle of a number of propulsion systems. The efficiency and the reliability of such engines directly depend on the characteristics and the behaviour of the droplets produced.


Air assisted atomisation of liquid films: experiments and simulations within the VAA project from the partner laboratories LEGI, IJLRDA, CORIA and IMFT

By combining the results of controlled experiments with direct numerical simulations, researchers from the “Virtual Assisted Atomisation” consortium have developed a model to better understand where the droplets are formed and in what amount, as well as to calculate their size and velocity.

This leading-edge numerical code gives unprecedented access to the computation of severe flow conditions, equivalent to those encountered in gas assisted injection systems used in aeronautic propulsion. The VAA consortium is now actively working on the optimisation of the code with the aim of reducing the computational time.
