The aim of this thesis is to develop a computer program to design and simulate air conditioning-comfort application of a selected building, for a year period, on an hourly basis. In order to carry out this study, a computer program named “AHUSIM.m”, is prepared with Matlab computing language. The design and simulation procedure starts with preparing the inputs like indoor, outdoor design states, zone cooling and heating loads, along with the general data for conditioning-comfort equipment. The program, in light of these input data, performs the plotting of the psychrometric processes -including the design and off design processes- on psychrometric charts, air conditioning-comfort system selection and calculating the response of this selected system at varying load conditions for a year. The program also calculates the energy requirements of parts of the selected system throughout the year. Furthermore, it lists dimensions of the parts of the air conditioning-comfort unit, the outdoor supply air and total air flow rates, air and water inlet and exit states. Using numerical tools for heating, ventilating and air conditioning (HVAC) process design and simulation, can improve energy economy and comfort which are the main criteria of HVAC engineering. In such an attempt, major concern is the interaction between the comfort and energy consumption. The program, by designing the system and deciding its behavior throughout a year; provides a means of automatic control considering comfort and energy economy. This program also provides a tool for comparison of different techniques for putting limits to the relation between comfort and energy consumption.

Development of a micro-fabrication process simulator for micro-electro-mechanical systems(mems) Yıldırım, Alper; Dölen, Melik; Department of Mechanical Engineering (2005) The aim of this study is to devise a computer simulation tool, which will speed-up the design of Micro-Electro-Mechanical Systems by providing the results of the micro-fabrication processes in advance. Anisotropic etching along with isotropic etching of silicon wafers are to be simulated in this environment. Similarly, additive processes like doping and material deposition could be simulated by means of a Cellular Automata based algorithm along with the use of OpenGL library functions. Equipped with an inte...
Development of an educational CFD software for two dimensional incompressible flows Nakiboğlu, Güneş; Sert, Cüneyt; Department of Mechanical Engineering (2007) The main purpose of this research is to develop a Computational Fluid Dynamics (CFD) software to be used as an educational tool in teaching introductory level fluid mechanics and CFD courses. The software developed for this purpose is called Virtual Flow Lab. It has a graphical user interface (GUI) that enables basic pre-processing, solver parameter and boundary condition setting and post-processing steps of a typical CFD simulation. The pressure-based solver is capable of solving incompressible, laminar, s...
Design scaling of aeroballistic range models Kutluay, Ümit; Balkan, Raif Tuna; Department of Mechanical Engineering (2004) The aim of this thesis is to develop a methodology for obtaining an optimum configuration for the aeroballistic range models. In the design of aeroballistic range models, there are mainly three similarity requirements to be matched between the model and the actual munition: external geometry, location of the centre of gravity and the ratio of axial mass moment of inertia to the transverse mass moment of inertia. Furthermore, it is required to have a model with least possible weight, so that the required tes...
Uncertainty analysis of coordinate measuring machine (CMM) measurements Sözak, Ahmet; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2007) In this thesis, the measurement uncertainty of Coordinate Measuring Machine (CMM) is analysed and software is designed to simulate this. Analysis begins with the inspection of the measurement process and structure of the CMMs. After that, error sources are defined with respect to their effects on the measurement and then an error model is constructed to compensate these effects. In other words, systematic part of geometric, kinematic and thermal errors are compensated with error modelling. Kinematic and geo...
Optimal external configuration design of missiles Tanıl, Çağatay; Platin, Bülent Emre; Department of Mechanical Engineering (2009) The main area of emphasis in this study is to investigate the methods and technology for aerodynamic configuration sizing of missiles and to develop a software platform in MATLAB® environment as a design tool which has an ability of optimizing the external configuration of missiles for a set of flight requirements specified by the user through a graphical user interface. A genetic algorithm based optimization tool is prepared by MATLAB is expected to help the designer to find out the best external geometry ...
