Comparison of analysis methods of embedded retaining walls
Harmandar, Serkan; Özkan, M. Yener; Department of Civil Engineering (2006)
In this study a single-propped embedded retaining wall supporting a cohesionless soil is investigated by four approaches, namely limit equilibrium, subgrade reaction, pseudo-finite element and finite element methods. Structural forces, such as strut loads, wall shear forces, bending moments are calculated by each method and results are compared. The analyses are carried for for three values of internal friction angle of soil; 30o, 35o, and 40o. Effects of modulus of soil elasticity of the backfill and wall ...
Experimental verification of CH4-CO2 swap in methane-propane-carbon dioxide mixture hydrates
Abbasov, Abbas; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2014)
Significant interest has been given to unconventional hydrocarbon resources in recent years. Natural gas hydrates are one of the key components of unconventional hydrocarbon resources to be addressed. However, energy utilization from hydrate reservoirs is challenging and related researches are still being carried out. Recently, a method in which methane gas (CH4) is recovered from natural gas hydrate formations by injection of carbon dioxide (CO2) has been proposed. This method is considered to be a promisi...
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.
Application of ultrasonic burning rate measurement method on closed bombs
Mumcu, Berkan; Kurtuluş, Dilek Funda; Arkun, Uğur; Department of Aerospace Engineering (2013)
In this thesis study, detailed information about solid rocket motors and ultrasonic burning rate measurement method is given. An experimental setup is prepared for applying the ultrasonic burning rate measurement method. Before performing the burning tests, some pre-tests are performed for affirming the ultrasonic sensor and obtaining some experimental coefficients. Two different types of propellants, which do not include aluminum, are produced for the burning tests. The first type of the propellants has tw...
