The performance of a domestic appliance for wood logs combustion is a function of several variables, such as the geometric design of the appliance and its operating parameters. Among them, air feeding conditions are really decisive if the objective function is the maximization of the heat recovered from flue gases. Therefore, even if pollutant emissions have to be ever considered, the amount of excess air can be seen as a fundamental parameter in the definition of thermal efficiency of the appliance.

Details on experimental procedure regarding rock cylinder and cement grout preparation, sample curing conditions, experimental apparatus, sample loading, mechanical characterization of the rock, and cement grout, along with procedures for the determination of the sample saturation assuming uniform saturation,...
Effect of Openings on the Seismic Response of AAC Infilled Frames
Todorovic, Lana; Demirel, İsmail Ozan; Binici, Barış (2019-10-11)
Autoclaved aerated concrete (AAC) is an attractive building material with lightweight, good insulation, fireproofing, and durability characteristics. The seismic response of AAC requires an in-depth understanding as its use as infill walls is gaining popularity in seismically active regions of many countries in Europe, Middle East, and Asia. Recent studies on the seismic response of AAC infill walls were mostly conducted on solid AAC walls without considering openings and simulated earthquake loading was ap...
Effect of non-condensable gases on the adsorption properties of adsorbent porous media
Bayman, Orhan Ata; Yamalı, Cemil; Department of Mechanical Engineering (2014)
Non-condensable gases such as air can penetrate into adsorption machines that utilize adsorbates which work at negative gage pressures. As many adsorption cooling/heat pump applications involve such negative gage pressures, it becomes important to research the effects of such non-condensable gases on the adsorption properties. In this thesis, prescribed amounts of air have been injected into an experimental apparatus containing an adsorbent bed and an evaporator/condenser to observe the effects of air on th...
Effect of polymer additives on the physical properties of bitumen based composites
Doğan, Mehmet; Bayramlı, Erdal; Department of Polymer Science and Technology (2006)
Polymer modified bitumen is a binder obtained by the incorporation of various types of polymers in bitumen using mechanical mixing or chemical reactions. There are several factors affecting the properties of polymer modified bituminous composites such as; chemical composition of bitumen, kind of polymer and filler, compatibility of bitumen and polymer, amount of bitumen, polymer and filler, particle size of filler and process conditions. The main objective of this study is to determine the effects of polyme...
