(Licenciatura em Engenharia Mecânica, ramo de Termodinâmica Aplicada, 5 years
course), Technical University of Lisbon, Instituto Superior Técnico, with 14val (within
a scale between 0 and 20). The final dissertation for attainment of the Diploma Engineer

dynamic behaviour of impinging droplets and was concluded in November of 2001,
with 18val.
2004 - M.Sc. in Mechanical Engineering. Thesis for attainment of the Degree of Master

University of Lisbon, Instituto Superior Técnico.
Former Activities and Present Studies/Professional Situation:
2001 – 2004 - I started my research activity in 2001, in the Center for Innovation,
Technology and Policy Research, IN+, during the final project for attainment of the
Diploma Engineer, working in the project “FLOW AND HEAT TRANSFER
CHARACTERISTICS
OF
EVAPORATING
IMPINGING
SPRAYS”,
Project
POCTI/1999/EME/32960, financed by the National Foundation of Science and
Technology – F.C.T and supervised by Prof. António Luís Nobre Moreira. The work
developed during my M.Sc. was also supported in this project, during which I held a
Research Grant.
The results of this work were published in several papers, mainly presented in
national and international conferences (one of these papers was selected to be published
at a journal). In addition, part of this study was included as a contribution for the
European project “DIRECT INJECTION ENGINE SPRAY PROCESSES –
MECHANISMS TO IMPROVE PERFORMANCE”, FP5, ENK6-CT-2000-00101.
2001-2002 - During the 1st semester of 2001/2002 I lectured the laboratory activities of
the course “Heat Transfer I”, of Year 4 of the Mechanical Engineering Degree.
2004-2007 - At the present moment I am a Ph.D. student of Mechanical Engineering, at
Technical University of Lisbon, Instituto Superior Técnico, supervised by Prof. António
Luís Nobre Moreira and my research work concerns Spray and Droplet/Wall interaction
processes. I am currently finishing my PhD dissertation, pending for the final exam for
defence of the thesis. I develop a research activity in a full-time basis, at IN+ - Center
for Innovation, Technology and Policy Research and I am supported by a fellowship
from the National Foundation of Science and Technology (ref.: SFRH/BD/18250/2004)
since November 2004. The main research work considers the study of the thermal and
fluid-dynamic mechanisms occurring at impact of droplets and sprays onto heated
surfaces. Main diagnostic techniques used are visualization with a high speed camera
and image processing and phase Doppler interferometry. The work developed during
the PhD, up to the present date, has been presented in various international conferences
and in three papers published at peer reviewed international journals (a fourth paper has
been recently submitted for publication at the Experiments in Fluids).
The research work developed during this period has also contributed to the
following projects (which partially supported the research activities):
“DYNAMIC BEHAVIOUR OF CRYOGENIC SPRAY COOLING”, Project
POCTI/EME/57944/2004. 2005-2008.
“FLOW AND HEAT TRANSFER CHARACTERISTICS OF EVAPORATING
IMPINGING SPRAYS”, Project POCTI/1999/EME/32960. 2001-2004.
“DIRECT
INJECTION
ENGINE
SPRAY
PROCESSES-MECHANISMS
TO
IMPROVE PERFORMANCE”, FP5, ENK6-CT-2000-00101. 2000-2003.
April 2005 – November 2005 – I undertook a training stage at the Thermofluids and
Heat Transfer Group – THT from the Engineering Faculty of Bergamo University,
under the supervision of Prof. G. E. Cossali and Prof. M. Marengo and co-supervision
of Doctor Maurizio Santini. This stage was financed by a Marie Curie Training Sites
Fellowship n. ENK-CT-2002-50518 and the experimental work was partly financed by
UE through the contract DITICE-2E0006R (sub-project of InteregIII-Regins). The work
developed during this stage evolved positively and resulted in a strong collaboration
between the research groups in Lisbon an in Bergamo. This work was presented in an
international conference and published in an international scientific journal.
2002-2007 – collaboration in the laboratorial activities and teaching (seminars) in
Experimental Methods in Energy and Environment (curricular unit of the 5th year of
Mechanical Engineering course - now re-structured as Mestrado Integrado in
Mechanical Engineering). The only exception was in the 1st semester of 2006 since I
was in the training stage at Bergamo University, in Italy. During this period I also gave
tutorial lessons in the subjects of Thermodynamics, Turbomachinery, Algebra, Calculus
and Physics.
February 2008 – I gave a lecture to the curricular unit of Integrated Energy Systems, in
the MIT Portugal Pos-Graduation Program, (EDAM – Engineering Design and
Advanced Manufacturing) at the Engineering Faculty of University of Minho,
Guimarães – Portugal.
During this current year I supervised the experimental work developed for the
dissertation for attainment of the Integrated Master Degree (post-Bologne) by two
students, one of them is an ERASMUS student from Roma University – Tor Vergata.
I’m a peer reviewer in Experiments in Fluids, Elsevier.
Main Scientific Area of Specialization:
Mechanical Engineering - Applied Thermodynamics: Fluid Mechanics, Heat Transfer,
Two-Phase Flows.
Research Activities and Present Research Interests:
My research activities and current research interests are mainly focused on the study of
the thermal and fluid dynamic mechanisms involved at droplet interactions with heated
walls, which is required for modelling of complex technological applications
considering spray impingement. Part of the work addresses the impact of fuel droplets
onto rough surfaces to quantity the effect of fuel properties and of the nature of the
surface in droplet dynamics, within the various boiling regimes, in the context of fuel
droplet/valve interactions in internal combustion engines.
Moreover it was necessary to deepen the study on the heat transfer mechanisms as
there are strongly related to the dynamic behaviour and morphology of the impinging
droplets. In this context a study is currently being conduced to infer on the effect of the
thermophysical properties of the working fluids, combined with the use of enhanced
surfaces with different topographies on the dynamics and heat transfer mechanisms and
determine the most favourable combinations of droplet, liquid and surface properties to
improve the cooling performance. In this context, the final part of my research work
under my Doctoral Programme also included the study of the thermal and fluid dynamic
processes occurring at the liquid-solid interface on micro-structured surfaces. Therefore,
the interfacial phenomena and the manufacturing processes of micro-structured surfaces
are currently my leading research interests, which I intend to deepen in a near future.
Different research groups have already shown interest in a strong collaboration for the
prosecution of this work under a post-doc Programme in Portugal, namely the research
THT Group at Bergamo University and the ITLR – Institute of Aerospace
Thermodynamics at Stuttgart University.
A particular emphasis is given to the influence of the nature of the surface
throughout this study, so the characterization of the wettability and topography of the
surfaces is an important part of the work. Therefore this work also required knowledge
on the wettability concepts and on some measurement techniques for characterization of
the contact angle as well as on the basic principles on the characterization of surface
topography. The background on the wettability concepts was provided in the Structural
Chemistry Center at Instituto Superior Técnico, which also provided the facilities to
measure the contact angles. The characterization of the topography of the structured
surfaces was performed in collaboration with the Department of Materials
Engineering at Instituto Superior Técnico and with the Laser Surface Processing
Laboratory of Faculdade de Ciências da Universidade de Lisboa.
