International Projects
1. Simulation of surface instability of a liquid pool subjected to a shear flow (by Nurdan
Yildirim).
The project has been done at Environmental and Applied Fluid Dynamics Department of Von
Karman Institute for Fluid Dynamics (VKI) Rhode Saint Genese, Belgium in 2005, supervised
by Prof. Dr. Jean-Marie Buchlin and Prof. Dr. Carlo Benocci.
Abstract: In this theoretical and numerical project, the physical mechanisms leading to the
production of surface waves generated at the interface of two fluids (liquid/gas or
liquid/liquid) are investigated. A particular attention is devoted to the Kelvin-Helmholtz type
instability appearing in the area of high shear located at the fluid-fluid interface. The
subsequent disturbances in velocity and pressure associated with the wave motion are assumed
2D and sufficiently small to justify the linearization of the equations of the motion. NavierStokes, Orr-Sommerfeld, Kelvin-Helmholtz Darcy (KHD) equations are mainly considered to
investigate the surface instability.
During the project, the main characteristics of surface instability such as wavelength,
amplitude, wave speed and growth rate are investigated according to various physical
parameters (density, surface tension, dynamic viscosity) of the fluids. The effect of the gravity
is analysed through 2D simulations configurations of horizontal flow as well as vertical coand counter flow configurations.
FFT analysis is providing the values of the dominant frequency and wavelength. This last
quantity is compared when the fluids are in the linear instability regime with KHD theory.
In spite of difficulties to extract the FFT contents, the results are matching well with the theory
for horizontal case. Prediction of the unstable region characteristics is possible with this
5
methodology together with the correct prediction of the transition of the waves from linear to
non-linear regime.
For vertical flow, the representation of the gravity field with the periodic assumption is
presenting a numerical difficulty to keep a constant mass flow rate for each individual phase.
2. Modelling of District Heating System for IZTECH Campus, Turkey (by Nurdan
Yildirim).
The project has been done at Geothermal Training Program of United Nations University,
Reykjavik-Iceland in 2002, supervised by Prof. Dr. Páll Valdimarsson (University of Iceland).
Abstract: The aim of this work is to determine best heating system for Izmir Institute of
Technology (IZTECH) Campus. IZTECH, founded in 1992, is the third university of Izmir,
the third largest city in Turkey. IZTECH campus has individual fuel boiler heating systems for
each faculty building since its foundation and the campus is still under development. In this
project three different district heating systems were studied and compared, using two different
heating strategies, intermittent and semi-intermittent heating. Mathematical models were
derived with programs using Matlab and EES (Engineering Equation Solver) written and run
using hourly weather data. In all, 50 heating alternatives with different parameters were
studied to determine the best heating system. The performance of these alternatives was
studied, regarding efficiency and estimated indoor temperature, and recommendations are
made. Besides heating system simulations, a network simulation was made using the software
Pipelab, which uses the Matlab program as a basis.

(The Impact of Thermal Comfort on the Building Energy Consumption for ClimaticRegions
of Turkey).
This project was funded by Turkish Society of HVAC and Sanitary Engineers (TTMD) during
2008-2010 and presented 10th REHVA World Congress, Clima2010, Antalya, Turkey, (9-12
May, 2010).
Abstract:Turkey is revising its legislations on building energy performance as foreseen in
EPBD (2002/92/EC), through the European Union accession process. Therefore, there has
been a growing interest in the evaluation of the heating/cooling energy consumption for
buildings. The assessment of the energy consumption for the climatic control of a building can
only be dealt with if the level of the indoor comfort is clearly defined. Since energy
consumption for heating/cooling is directly affected by the required level of thermal comfort,
the study aims to investigate the relationship between thermal comfort and energy
consumption of the residential buildings for different climatic regions of Turkey. Once a range
of required acceptable indoor operative temperatures had been fixed in accordance with
Fanger’s theory, the monthly averages of hourly comfort conditions and the energy
consumptions were estimated through dynamic simulations for continues and intermittent
operating modes.

(Evaluation of Geothermal Energy Projects in Turkey in the Context of the Clean Energy

This project was funded by TUBITAK. Chapter 2 ( (Jeotermal Uygulamaların Çevresel
Etkileri (Environmental Impacts of Geothermal Applications)) and Chapter 9 (Çevresel Etki
Değerlendirme (Environmental Impact Assessment)) were prepared by Nurdan Yildirim in
2008.
Abstract: Geothermal energy applications either electricity generation or heating have positive
and negative physical, chemical, biological and social-economical effects on the environment.
To present these effects with an example Kızıldere Geothermal Power Plant and Balcova
Geothermal District Heating System are chosen as the main application areas of geothermal
energy. The aim of the project is to assess the environmental impacts of both applications.
Depending on their source temperature and the process, the impacts exhibit difference. The
result of data acquisition, chemical analysis and measurements gives us the pollution potential
of both applications. Environmental effects, especially at geothermal power plants which use
high temperature geothermal fluids, can be reduced by applying “Environmental Impact
Assessment” at design stage and/or can be avoided by a careful project management at
operation stage. Depending on pollution potential, during the application and operational stage
of the projects, the necessity of “Environmental Impact Assessment” process is emphasised.
