Hydrodynamic Optimization of the Submarine with a Fully Parametric CAD Model
(Fen Bilimleri Enstitüsü, 2023-02)
This study was conducted to compare the performance of four different optimization
studies that can be done to reduce the drag force that a submarine is exposed to in fully
submerged conditions. The submarine used in the ...
Broadband and High Frequency Piezoelectric Energy Harvesting System With Curved Panels For Passive Vibration Isolator
(Fen Bilimleri Enstitüsü, 2023-02-01)
In military aircrafts, random vibration occurs with high amplitude in broad frequency
spectrum. High vibration profiles, which affecting electronic units, can cause fatigue over
time and damage mechanics and electronic ...
Modelling and Analysis of Legged Robots with Temporary Flight Capabilities
(Fen Bilimleri Enstitüsü, 2022)
The high obstacle-crossing potential of legged robots has made them a widely studied subject. However, the obstacles that can be overcome are generally proportional to the length of the legs. And any study, that states a ...
Intelligent Control of Refrigerators and Freezers
(Fen Bilimleri Enstitüsü, 2022-12)
As the number of consumers has been growing and global warming continues to affect the environment, the refrigeration sector is becoming an increasingly important part of the global economy. Refrigeration products have ...
Thermal Behavıor of Lıthıum-Ion Batterıes Under Normal and Abuse Operatıng Condıtıons
(Fen Bilimleri Enstitüsü, 2022)
This doctoral thesis investigates the electrical and thermal behaviors of Li-ion battery cells during the normal and abnormal conditions using the experimental and modeling methods. First, various standard battery tests ...
Kinematic Design and Analysis of Munition Ejector Release Unit
(Fen Bilimleri Enstitüsü, 2023)
In this study; design, analysis and optimizations will be done to open the hanger handles at fixed intervals on the ammunition attached to a release mechanism. The hook arms are held by the mechanism and release the hook ...
Multibody Simulation of Coupled Aerodynamics and Structural Model of a Helicopter Main Rotor
(Fen Bilimleri Enstitüsü, 2023-02-02)
The use of helicopters has been on the rise since their invention, particularly due to their ability to perform axial and hover flights. However, designing a helicopter rotor is a complex process, as it involves understanding ...
Dynamic Characterisation of Human Neck For Impact Applications
(Fen Bilimleri Enstitüsü, 2023)
The neck is the part of the spine and has highest risk of injury in traffic accidents. Neck trauma can occur in several types of collisions, but rear-end collisions have the highest risk of trauma. Human neck models are ...
Impeller Burst Analysis and Validation
(Fen Bilimleri Enstitüsü, 2022-12-15)
The rotating parts in gas turbines are expected to operate safely under different loads, such as
high centrifugation, temperature, and pressure. Due to the high centrifugal forces generated
at high rotational speeds, ...
Immersed Boundary Method for Rotorcraft Aerodynamics Using OpenFOAM
(Fen Bilimleri Enstitüsü, 2022)
The rotorcraft CFD literature review showed that efficient, easy to apply, and computationally
less expensive methods are still a need for the design and performance predictions of
rotorcraft. Immersed Boundary Method ...
