This site is a part of the work in the Industrial Engineering consulting  Energetic and Process.

The Industrial Engineering consulting BEI is a long project implemented within the Hydraulic Department and Fluid mechanics of ENSEEIHT by its various specialities Process and Energetic (E&P) and Computational fluid dynamics (MFN).

The aim of these BEI is to work in groups of 3 students on scientific projects proposed by industrial collaborators.

During our BEI, we will provide a study on Evaporation of fuel layer by elaborating a physical problem modeling. We will establish a theoretical analysis by treating all the physical phenomenon relevant to the problem such as diffusion and convection. The second part of the BEI is to implement a numerical simulation using OpenFoam for several configurations of this study.




The team that is working on this project comprises three students:

          Geremia Giuliano Alejandro: 3rd year at ENSEEIHT, Computational fluid dynamics (MFN)

          Mezguledi Ansar                   : 3rd year at ENSEEIHT,  Process and Energetic (E&P)

          Quentin Mouret                    : 3rd year at ENSEEIHT, Process and Energetic (E&P)




This BEI is supervised by Mr. Dominique Legendre a research and teaching professor at IMFT-ENSEEIHT.



Industrial environment and objectives

& Objectives   


          1- Industrial environment

    The aeronautical sector is at present an ultra-competitive sector. With the arrival of new Russian and Chinese competitors, both big actors of this sector, Airbus and Boeing, have to step up their ingenuity and innovation to keep their leaderships and to deal with new markets.

    So they are developing at present new models of planes which are lighter, more aerodynamic and less consumer. They aim maintain a distance from their competitors and the new incomers.

     It is in this rough economic environment that Airbus requested this study in collaboration with Altran, the IMFT (Institute of Fluid mechanics of Toulouse) as well as the Hydraulic Department and Fluid mechanics of the ENSEEIHT.


           2- Industrial partners

  • Airbus

    Airbus SAS is an aircraft manufacturing subsidiary of EADS, a European aerospace company. Based in Blagnac, France, a suburb of Toulouse, and with significant activity across Europe, the company produces approximately half of the world's jet airliners.



    Airbus employs around 63,000 people at sixteen sites in four European Union countries: France, Germany, the United Kingdom and Spain. Final assembly production is based at Toulouse, France; Hamburg, Germany; Seville, Spain; and, since 2009, Tianjin, China. Airbus has subsidiaries in the United States, Japan, China and India.
The company produces and markets the first commercially viable fly-by-wire airliner, the Airbus A320, and the world's largest airliner, the A380.


  • Altran Technologies


    Altran Technologies, SA is a European consulting firm founded in 1982 in France. Altran, self dubbed the European leader in high technology and innovation consultancy, operates primarily in technology and innovation consultancy, accounting for nearly half of its turnover. Administrative and information consultancy accounts for a third of its turnover with strategy and management consulting making up the rest.


Mission & Planning

Mission & Planing                                 


           1- Mission

    Under this project, it was asked to realize the study of a thin layer evaporation. This one is in line with the necessity of Airbus to reduce the weight of its planes.

Indeed, there are, at present, fuel leaks in the piping which allows to forward the fuel of the reservoir up to the engines of the turbomachinery of planes. This fuel is got back by reservoirs which are oversized.

Moreover, the flammability increases according to the concentration of the fuel in the air. It is for this that it will be necessary to limit the values of this concentration.

This project aims to study the evaporation of a thin layer of the liquid to be able to re-size reservoirs getting back fuels and this to decrease recirculations there.

 Both theoretical and numerical study on the evaporation of a layer of fuel in such reservoir will thus be performed in this BEI.
