The Research experiences of the author before his coming at LCPC (Laboratoire CEntral des Ponts et ChaussÃ©es) has started during his PhD (2003-2006) which has been completed by an internship abroad under an European Marie Curie fellowship (2004) and a post-doctoral position (2007-2008). They were conducted in several laboratories: â€¢ The laboratory of Process Engineering, Environment, Food (GEPEA-UMR CNRS 6144) of Nantes / Saint-Nazaire and the Laboratory ICPF (Institute of Chemical Process Fundamentals) of the Academy of Sciences Czech Republic in Prague. The aim of the PhD was to initiate activity "Microfluidics and miniaturization processes" in the laboratory GEPEA. The originality of this work was based on the implementation of different methods used in characterization of local transfer (mass and momentum) at different scales of the processes (from micro-scales to milli-scales) and was recognized by the scientific community (4 international publications). Several training were supervised by F. Huchet. Among them, two students in Research Master for which two international publications have been published about their experimental works. â€¢ The Laboratory of Biotechnology and processes ( LISBP-UMR 5504 CNRS / INRA / INSA) at INSA Toulouse as post-doctorate position from November 2006 where his researches was devoted to the analysis of mixing heterogeneities in bioreactors in the frame of an white ANR (IDyBioPBioP). The aim was to identify the parameters that act directly on the performance of a bioprocess whose the turbulent mixing. This experimental study was devoted to the pilot-scale and realized in close collaboration with IMFT (Institute of Fluid Mechanics of Toulouse). The results were the subject of an international publication and a recent oral conference ("13th European Conference on Mixingâ€). Hired from 1st September 2008 at the unit Sustainable Approaches in Civil Engineering (DDGC) at Laboratoire Central des Ponts et ChaussÃ©es (LCPC), the research activities of F. Huchet is in conjunction with his skills in process engineering. His research project is aimed at the energy assessment of the manufacture of asphalt mixing plant in two main ways: The first is to remove scientist barriers to the modelling of transfer phenomena (momentum, heat and mass transfer) inside unit operations of the asphalt-plant. The second is to find new way for energy optimization process.
