The case of combined conduction, convection and radiation heat transfer usually occurred in solar
thermal usages is the aim of the present study. Several configurations of solar air heaters (SAHs)
have been developed in literature in searching of a suitable design for different types of
applications, various designs of solar collectors have been the subject of many theoretical and
experimental investigations. In thermal devices, improvement of convection heat transfer
becomes an important factor in industries like electronic equipment and heat exchangers.
In industrial processes, another method for improving the convection heat transfer characteristics
is using porous medium(any material which consists of solid matrix with an interconnected void is
called porous media such as rocks and open cell aluminum foams) and nanofluid. Convection heat
transfer and fluid flow with nanofluids and porous medium occur in power stations of many
engineering applications where cooling or heating is required such as cooling turbine blades,
cooling electronic equipment and combustion systems.
This research also focus program aims to obtain lab‐scale nanofluid which will be built in two
stages. In this project fluid phase, is silicone oil with temperatures between 200 and 300 Celsius
degrees and nanoparticles are silica nanostructures with different morphologies and sizes, silicon
carbide and silicon dioxide nano‐structures will be spread in silicon oil with different volume
percentages (1‐5%).stability of the mixture is one of the most important issues and will be
examined with a suitable method such as zeta potential and particle size and the heat transfer
properties of oil at high temperatures will be examined with various analyzes such as DSC analysis,
also K coefficient will be examined.
Main targets:
Due to their excellent characteristics, nanofluids find wide applications in enhancing heat transfer.
The aim of this appraisal Research Areas (RA) is the methodology study as an experimental setup
of the nanofluids in solar thermal Energy applications.
In order to overcome these drawbacks, achievement of direct solar thermal absorption collector
has been used for solar thermal exploitation.
Hence it will be a promising effort to develop research projects on the use of nanofluids in
different solar thermal systems such as solar absorption, solar thermoelectric cells, and thermal
conductivity of nanofluids, electronic applications, energy storage and solar absorption.

Energy-modeling is the virtual or computerized simulation of a thermal-electrical energy for building or
every complex that focuses on modeling energy consumption, utility and life cycle of various energy related
items such as thermal hot water ,air conditioning and also solar power plants or lights. It is also used to
evaluate the simulation and modeling of solar thermal technology using nano-energy such as modeling of
thermal conductivity or heat transfer by nanofluids or porous-media for every energy systems.
Nanofluids are prepared by dispersing solid nanoparticles in fluids such as water, oil, or ethylene glycol.
These fluids represent an innovative way to increase thermal conductivity and, therefore, heat transfer. Unlike
heat transfer in conventional fluids, the exceptionally high thermal conductivity of nanofluids provides for
exceptional heat transfer, a unique feature of nanofluids.
This Research area presents a novel model for the prediction of the effective thermal conductivity of
nanofluids based on dimensionless groups. The model expresses the thermal conductivity of a nanofluid as a
function of the thermal conductivity of the solid and liquid, their volume fractions, particle size and interfacial
shell properties.
According to this model, thermal conductivity changes nonlinearly with nanoparticle loading. The results are
in good agreement with the experimental data of alumina-water and alumina-ethylene glycol based
nanofluids.
The work addresses the utilisation of all resources and all technologies to understand what is happening and
what will happen to the energy system. Through our energy scenario program work we also seek to
identify how country are addressing the challenge and how country and key stakeholders can put in place
policies and structures to deliver a sustainable energy system.The net energy consumption in the scenarios has
been calculated on the basis of a consumption model of energy consumption in 2035 and 2050 analysed by
quality of energy at three different levels of energy savings (moderate, large and extra-large savings).The
following is included: electricity, district heating, process heating, individual heating, and energy for transport
(including aviation and domestic shipping).
Main targets: In this area, Simulation and Modelling of an energy systems as the energy efficiency,
achievement of high efficiency, exergy loss, friction factor, and pumping power parameters were analyzed to
determine the thermal performance of different energy systems like nanofluid coolants in a rectangular
microchannel heat sink and etc.
