In line with current international trends, EREL places
emphasis in R&D activities relevant to hydrogen technology,
simulation of atmospheric pollutant dispersion in realistic
conditions, diagnostic and prognostic meteorological
modelling, contribution of anthropogenic and biogenic
pollutants to global warming and urban pollution, simulation
of underground hydrocarbon and water reservoirs and
characterization of nanoporous materials for environmental (gas
separations, storage of CO2 and H2) and bio-medical
applications (controlled release systems, transdermal drug
delivery). In parallel, EREL continues to produce and
publish original methods and results in the wider area of
computational fluid mechanics, with applications in
pollutant dispersion, influence of meteorology and pollutant
sources distribution in urban pollution, tropospheric ozone
concentrations due to anthropogenic and biogenic pollutants
in the Mediterranean area, turbulence simulation, transport
phenomena in porous media, and flow and mass transport in
multiphase systems. The high R&D performance of EREL is
deduced from: (i) its wide experience in carrying out (not
only as participating research organisation but also as
coordinator) large scale research projects, (ii) the large
number of scientific publications in international journals
and conferences, (iii) the successfully accomplished
contracts of service provision to Public and Private Bodies,
(iv) the organisation of international conferences, (v) the
participation in International networks and (vi) acting as
national representative in various international
organisations. |

The laboratory conducts mainly
applied research and experimental development, arising from
the needs of the productive sector, the ties with which have
been built through the services offered by the laboratory in
a wide field of applications and over a number of years.
However, in this effort the laboratory personnel is often
faced with the need to answer questions that concern
fundamental physical phenomena and expand the current
knowledge, especially in the fields of fluid flow, heat/mass
transfer and thermodynamics. Therefore, problems are often
dealt with at the basic research level, by using suitable
analytical methods (modelling and simulation) along with
experimental methods.
The specific research areas of SESL are : |
|
|
| The laboratory has been providing
reliable and high quality accredited (according to EN ISO/IEC
17025) services to the productive sector, located in Greece
but also abroad, as following: |

Risk Assessment of Complex
Systems
The complexity, the severe consequences, the huge costs
and the relative scarcity of catastrophic failures do not
permit a standard approach, according to which improvements
and relative measures could evolve only by analyzing past
experience (real facts) or experiments. The probabilistic
analysis and risk assessment approach can (without any
historical data) simulate and calculate all possible
consequences, and all event sequences that lead to those
consequences and the probability of their appearance. |
| |
Risk Management
Risk Management refers to decision making concerning
alternative courses of action with the aim of reducing risks.
It usually takes the form of supporting relevant decisions
taking into consideration the effect on risk. |
