ABOUT LASEF



 

 

LASEF, the Laboratory of Simulation in Energy and Fluids, is a research unit of IST/IDMEC (Instituto de Engenharia Mecânica, located at Instituto Superior Técnico) aiming to be a center of excellence on the numerical methods used for modelling the physical phenomena. It's expertises lie in anything related to fluid dynamics and applied thermodynamics. Nonetheless, due to LASEF's involvement with the industry, a larger body of knowledge and know-how was developed in areas such as structural mechanics,  electromagnetism, and many others.

 

LASEF was founded in 1992 by José Carlos Fernandes Pereira, a full professor of IST. Now, more than 20 years later, it has grown from a very small group of researchers and experimentalists to a group of more than 30 people doing R&D full-time, with more than 40 published papers, books and conferences. The work of LASEF has been certified as excellent (see, for example,  these avaliation reports) and recognized by institutions like the portuguese bank Santander Totta and the german research organization, the Fraunhofer Institute, which have awarded the excelence of the work developed. LASEF has also worked in numerous projects with world-renown companies (such as Siemens, Volkswagen, Denso, JDEUS Thermal Systems), research centers and Universities (NTUA, TUFrieberg, ...) and has received funding from the EU, FCT, QREN, Fomentinvest, among others.

 

 Here are some general, but not extensive, applications and extra information about LASEF:

Turbulence is the most important unsolved problem of classical physics. (Richard Feynman)

 

I am an old man now, and when I die and go to heaven there are two matters on which I hope for enlightenment. One is quantum electrodynamics, and the other is the turbulent motion of fluids. And about the former I am rather optimistic. (Horace Lamb)
