Experimental and computational activities were performed to determine the possible improvements of total environmental impact of a wood-open fireplace. Two models of fireplaces will be discussed, both with the same power and with only a difference relative to the geometry of the internal elements of the heat exchanger. In the second model the two blades have been substituted with one pipe that represents a possible and cheaper solution in the way of optimization. The optimization process has been conducted up to the determination of a third configuration with a better thermal efficiency. While combustion emissions are difficult to reduce where only a minimum control of actual combustion conditions can be ensured in such domestic appliances, a significant improvement can be considered for the heat recover efficiency. This improvement can be achieved through a detailed analysis of the thermal conditions realized and can require modifications to the heat exchanger geometry profitable from the manufacturing point of view too.

Assessing thermal performance of office building envelopes : a case study on energy efficiency
Sürmeli, Ayşe Neşen; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2004)
In this study, the energy conservation potential of selected retrofitting interventions on an office building were investigated, on the basis of which some rational strategies for the improvement of building envelopes in terms of energy, environment and comfort design were proposed. Examined were various measures on envelope constructions that can be retrofitted to existing buildings. By using simulation techniques, the effectiveness of such measures in reducing energy consumption and environmental threat w...
Numerical modeling of Edremit geothermal field
Günay, Emre; Karahanoğlu, Nurkan; Department of Geological Engineering (2012)
The purpose of this study is to examine the geothermal potential, sustainability, and reinjection possibility of Edremit geothermal field. In order to investigate this, a numerical model consisting of a hot and cold water aquifer system is established. A two dimensional cross sectional model is set to simulate this geothermal system. Different pressure and temperature values are applied to the nodes at the boundaries to perform a steady state calibration which minimizes the computed results and observed val...
Photovoltaic power plant design considering multiple uncertainties and risk
Merzifonluoglu, Yasemin; Uzgoren, Eray (2018-03-01)
The objective of this study was to develop stochastic optimization tools for determining the best strategy of photovoltaic installations in a campus environment with consideration of uncertainties in load, power generation and system performance. In addition to a risk neutral approach, we used Conditional Value-at-Risk to estimate the risk in our problem. The resulting Mixed Integer Programming models were formulated using a scenario-based approach. To minimize the mismatch between supply and demand, hourly...
Comparison of iscst3 and aermod air dispersion models: case study of cayirhan thermal power plant
Dölek, Emre; Atımtay, Aysel; Department of Environmental Engineering (2007)
In this study, emission inventory was prepared and pollutant dispersion studies were carried out for the area around Çayırhan Thermal Power Plant to determine the effects of the plant on the environment. Stack gas measurement results were used for the emissions from the power plant and emission factors were used for calculating the emissions from residential sources and coal stockpiles in the study region. Ground level concentrations of SO2, NOx and PM10 were estimated by using EPA approved dispersion model...
In situ examination of structural cracks at historic masonry structures by quantitative infrared thermography and ultrasonic testing
Tavukçuoğlu, Ayşe; Grinzato, E. (2010-01-01)
The key concern of the study was the in situ assessment of cracks in historic masonry structures by quantitative IR thermography (QIRT). To better understand the potentials and/or limits of QIRT for that purpose, the non-destructive in situ survey composed of QIRT and ultrasonic testing was conducted on a sixteenth century monument, suffering from structural cracks that had occurred in recent years. Its aim was to discover the thermal behaviour and ultrasonic characteristics of cracks in relation to depth a...
