Analysis of crack initiation and propagation in solid rocket motor nozzle throats
Nigar, Barış; Özerinç, Sezer; Department of Mechanical Engineering (2019)
Graphite is a widely used material in high temperature structural applications due to its high melting point and its mechanical strength and integrity at elevated temperatures. However, rocket nozzles made of graphite are subjected to very high temperatures and pressures that cause cracking and eventual failure. This thesis investigates the reasons of failure and explores design alternatives to overcome this problem. The experimental part of the thesis includes compression tests, tensile tests and fracture ...
Non-reacting CFD analysis of a drop tube furnace used for solid fuel combustion
Gülenç, Gamze; Kazanç Özerinç, Feyza; Department of Mechanical Engineering (2017)
In this thesis, the flow inside the drop tube furnace (DTF) which was already built in the Clean Combustion Technologies Laboratory located in Department of Mechanical Engineering at Middle East Technical University is analysed by using Computational Fluid Dynamics method. DTF is a semi-pilot scale electrically heated reactor with the aim of achieving constant temperature zone to investigate combustion characteristics of solid fuels. A simplified geometry is created for the flow analysis inside the DTF. The...
Experimental study of solid propellant combustion instability
Çekiç, Ayça; Ulaş, Abdullah; Department of Mechanical Engineering (2005)
In this study, experimental investigation of solid propellant combustion instability using an end burning T-Burner setup is performed. For this purpose, a T-Burner setup is designed, analyzed, constructed and tested with all its sub components. T-Burner setup constructed is mainly composed of a base part, a control panel and the T-Burner itself. Combustion chamber, pressure stabilization mechanism, pressurization system, measurement instruments and data acquisition systems form the T-Burner. Pressure stabil...
Thermal radiation from solid propellant rocket motor plume
Özen, Güzide; Selçuk, Nevin; Department of Chemical Engineering (2015)
Radiation emitted from rocket plumes plays a significant role in quantifying infrared (IR) radiative signature which is essential for identification and tracking of rockets. Prediction of plume radiation necessitates simultaneous solution of conservation equations for mass, momentum, energy, chemical species and radiant energy to provide input data for the radiation code. This is carried out by a Computational Fluid Dynamics (CFD) solver. As CFD solvers are CPU time expensive, an accurate and CPU efficient ...
Analysis of grain burnback and international flow in solid propellant rocket motors in 3-dimensions
Yıldırım, Cengizhan; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2007)
In this thesis, Initial Value Problem of Level-set Method is applied to solid propellant combustion to find the grain burnback. For the performance prediction of the rocket motor, 0-D, 1-D or 3-D flow models are used depending on the type of thre grain configuration.
