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...
Ultrasonic measurement of solid propellant burning rates in closed bombs and subscale motors
Atak, Özen; Yamalı, Cemil; Department of Mechanical Engineering (2016)
In the scope of this thesis, applications of ultrasonic measurement method on closed bombs and test motors were investigated with various aluminized and nonaluminized propellants with the main target of evaluation of burning rates. Detailed comparison between conventional methods for solid propellant burning rate measurements such as strand burner, firing of subscale test motors and ultrasonic measurement was performed. Burning rate evaluation of eight propellant batches were determined by thirty three clos...
Structural and optoelectronic properties of vanadium pentoxide thin films deposited by ultrasonic spray pyrolysis.
Koç, Şeyma; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2019)
Nanocrystalline vanadium pentoxide (V2O5) thin films were deposited onto fluorine doped tin oxide (FTO) coated glass substrates using ultrasonic spray pyrolysis and spin coating methods. The formation behavior of thin films, the effects of different production methods on the characteristics of the films and their microstructural / physical properties were investigated as a function of annealing temperature in the range of 450-550 °C and other controllable process parameters. Structural, morphological and op...
Effects of ultrasound pretreatment and anaerobic digestion on the energy potential of sludge
Çelebi, Emrehan Berkay; Sanin, Faika Dilek; Aksoy, Ayşegül; Department of Environmental Engineering (2015)
The by-product of wastewater treatment, sludge, is generated in tons everyday all around the world. As environmental regulations in Turkey are becoming stricter during the European Union adaptation period, the previously wide-spread disposal method of landfilling the sludge will not be applicable. Instead, dried sludge is expected to be used in revenue generating methods like land application or combustion. Combustion can be thought of as more beneficial as it uses sludge as an energy source. However, it is...
Development of piezoelectric ceramics for ultrasonic motor applications
Kalem, Volkan; Timuçin, Muharrem; Department of Metallurgical and Materials Engineering (2011)
This study has been carried out to develop and manufacture piezoelectric ceramic materials which are utilized for ultrasonic motor (USM) applications. For this purpose, the effect of compositional modifications on the dielectric and piezoelectric properties of lead zirconate titanate (PZT) based ceramics was investigated. PZT based powders were produced using the mixed oxide method. The base composition was selected as Pb(Zr0.54Ti0.46)O3. The samples in the proximity of morphotrophic phase boundary were dop...
