This paper discusses the development of an in-house computer code for the thermal analysis of satellites. The code uses Thermal Network Method (TNM) in conjunction with the Method of Lines (MOL) for the solution of the energy equation in the presence of radiative heat transfer. The predictive accuracy of the code is demonstrated on a test problem involving a cubic satellite with two solar panels and a single representative payload at its center to account for all other possible equipments in the satellite. The results produced by the present code were compared with the predictions of commercial thermal analysis software on the same test problem and a good agreement between the two sets of results was obtained. The code is a promising tool for the thermal analysis of satellites.

Thermal network method applications to problems related with the thermal analysis of small satellites. Okan, Altuğ; Çelenligil, M. Cevdet; Tekinalp, Ozan; Department of Aeronautical Engineering (2002) In this thesis, the thermal network method is examined in detail and is applied to some problems related with the thermal analysis of small satellites. In satellites, dominant modes of heat transfer are the thermal radiation and conduction. In this research, energy exchanges among the surfaces of satellites are investigated. Also, the radiation exchange factors are determined which are necessary in radiation thermal analyses. A FORTRAN code 'TRANS" is developed. This code uses the thermal network method for...
DEVELOPMENT OF SMALL SIZE UNCOOLED INFRARED MICROBOLOMETER PIXEL Tekin, Baran utku; Akın, Tayfun; Turan, Raşit; Department of Micro and Nanotechnology (2021-9) This thesis reports the development of 12 µm pixel pitch single layer microbolometer structures for use in the 8-12 µm wavelength regions, following recent trends in the last decade in microbolometers. Various pixel structures are designed, simulated, fabricated, and characterized to obtain acceptable detector performance in these small pixels. The pixel structures are improved by reducing the pixel thermal conductance and by using planar type electrode structures where the active material is selected as V...
Development of a software for determination of kinetic parameters in thermal analysis Ertunç, Göker; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2011) In this thesis, a new software, THERA-Kinetics was developed for the evaluation of kinetic parameters using non-isothermal data. Different computational methods, available in the software, were applied to a set of experimental and simulated data distributed in the ICTAC (International Confederation for Thermal Analysis and Calorimetry) Kinetics Project. The reliability of the software was verified by comparing the kinetic results, which were in good agreement, with those obtained by the participants of the ...
The method of lines solution of discrete ordinates method for radiative heat transfer in cylindrical enclosures Harmandar, S; Selçuk, Nevin (2004-04-01) A radiation code based on method of lines solution of discrete ordinates method for radiative heat transfer in axisymmetric cylindrical enclosures containing absorbing-emitting medium was developed and tested for predictive accuracy by applying it to (i) test problems with black and grey walls (ii) a gas turbine combustor simulator enclosing a non-homogeneous absorbing-emitting medium and benchmarking its steady-state predictions against exact solutions and measurements. Comparisons show that it provides ac...
Electromagnetic Scattering from Obstacles in the Near Field Region of Electrically Large Arrays Cetin, Ramazan; Aydın Çivi, Hatice Özlem; Nepa, Paolo; Manara, Giuliano (2009-09-18) In this paper, an efficient method for the analysis of electromagnetic scattering/radiation from the obstacles nearby electrically large array antennas, with nonuniform excitation, is proposed. The approach is based on the combination of a ray field representation of electrically large arrays and a DFT (Discrete Fourier Transform) based representation of array current distribution. Proposed method is applied to a 2D problem: Radiation of a linear array of 2N+1 infinitely long current elements with tapered c...
