"A New Algorithm for Solution of the Non-Linear Equation Systems Occurring in the Design of Air Compression Systems"

Sözbir, Nedim; Uysal, Ünal; Güven, Hasan Rıza (1994)
A new approach to the simulation of thermal systems

Sözbir, Nedim (ASME-AMER SOC MECHANICAL ENG, 2006)

In this paper, thermal systems are simulated and analyzed with a new approach. Thermal system design equations can be obtained as a nonlinear algebraic equation system and then this nonlinear equation system is converted ...
A Practical Launcher Thermal Analysis Tool for Three-axis Stabilized GEO Communication Satellites

Murat Bulut; Sözbir, Nedim; A Hacioglu; Mf Unal; Altan, Ozan; M Yorukoglu; Ms Yildiz (IEEE, 2017)

The Practical Launcher Thermal Analysis Tool can be a useful tool for the early design stage of three-axis stabilized GEO communication satellites.
A Review of Vapor Chambers

Murat Bulut; Satish G. Kandlikar; Sözbir, Nedim (TAYLOR & FRANCIS INC, 2019)

Future developments in electronic industries will require efficient cooling systems to dissipate large amount of heat produced over a small area. In recent years, interest has grown in extending the use of vapor chambers ...
Analytical investigation of a nanosatellite panel surface temperatures for different altitudes and panel combinations

Murat Bulut; Sözbir, Nedim (PERGAMON-ELSEVIER SCIENCE LTD, 2015)

The thermal control of future nanosatellite will be challenging due to dedicated panel surface area for radiation. The thermal control concept is to keep the payload within allowable temperature ranges. In order to predict ...

Selman Demirel; Özbey, Şerafettin; Sözbir, Nedim; Senol Gulgonul (ST JOHN PATRICK PUBL, 2015)
EXPERIMENTAL MEASUREMENTS AND COMPUTATIONAL MODELING FOR THE SPRAY COOLING OF A STEEL PLATE NEAR THE LEIDENFROST TEMPERATURE

Yiğit, Cemil; Sözbir, Nedim (TURKISH SOC THERMAL SCIENCES TECHNOLOGY, 2011)

Experimental studies and numerical simulations were conducted to reveal the heat transfer mechanism of impacting water mist on metal surfaces heated temperatures ranging from nucleate to film boiling regime. The test ...
Experimental study and artificial neural network modeling of unsteady laminar forced convection in a rectangular duct

Sözbir, Nedim; Ekmekçi, İsmail (SPRINGER, 2007)

In this study, an artificial neural network (ANNs) for the prediction of unsteady heat transfer in a rectangular duct was studied. The ANNs has been applied for the unsteady heat transfer in a rectangular duct. An experimental ...
Heat transfer of impacting water mist on high temperature metal surfaces

Sözbir, Nedim (ASME-AMER SOC MECHANICAL ENG, 2003)

Experimental studies were conducted to reveal the heat transfer mechanism of impacting water mist on high temperature metal surfaces. Local heat transfer coefficients were measured in the film-boiling regime at various air ...
MULTIPHASE SPRAY COOLING OF STEEL PLATES NEAR THE LEIDENFROST TEMPERATURE - EXPERIMENTAL STUDIES AND NUMERICAL MODELING

Sözbir, Nedim; Yiğit, Cemil; Güven, Hasan Rıza (BEGELL HOUSE INC, 2010)

Numerical modeling of a ground source heat pump: The Bolu case

Unal Camdali; Murat Bulut; Sözbir, Nedim (PERGAMON-ELSEVIER SCIENCE LTD, 2015)

The purpose of this study is to present the numerical modeling techniques for a Ground Source Heat Pump (GSHP): The Bolu case. Numerical modeling of the GSHP system with horizontal ground heat exchangers operating in heating ...
Prediction of the Solar Array Temperatures of Geostationary Earth Orbit Satellite by Using Analytical Methods

Murat Bulut; Sözbir, Nedim (IEEE, 2019)

The temperature of the solar array is a very important parameter for the solar array efficiency and needs to be calculated. In this study, a three-axis stabilized type satellite was used to predict the solar array temperatures ...
Spray mist cooling heat transfer in glass tempering process

Sözbir, Nedim; S. C. Yao (SPRINGER, 2017)

Energy saving is a very important issue in glass plants, especially in a glass tempering process, where very high velocity air jet impingement is applied during the cooling process of glass tempering. In fact, air compressor ...
The Effect of Uncertainty Values of Thermal Control System on GEO Satellites

Erkam Arslantas; Murat Bulut; Sözbir, Nedim; A Hacioglu; Mf Unal; Altan, Ozan; M Yorukoglu; Ms Yildiz (IEEE, 2017)
