EXPERIMENTAL INVESTIGATIONS AND COMPUTATIONAL FLUID DYNAMIC PREDICTIONS OF PRESSURE DROP CHARACTERISTICS IN MULTIPHASE FLOW FOR CONCENTRIC INCLINED ANNULI IN NEAR HORIZONTAL WELLS
(Mechanical Engineering, 06-2 , Master Thesis)
In oil and gas sectors, the accuracy of pressure drop predictions plays significant role in designing multiphase flow systems. In recent decades, there is a considerable amount of theoretical and experimental studies dealing ...
THE EFFECT OF GROOVING, EXTERNAL, AND INTERNAL GFRP OVERWRAPPED PVC TUBES ON CRASHWORTHINESS CHARACTERISTICS
(Mechanical Engineering, 06-2 , Master Thesis)
Several factors that affect the crashworthiness characteristics were investigated using GFRP overwrapped PVC composite tubes. Composite tubes studied alongside the PVC were non-grooved tubes wrapped externally or internally, ...
SUPPLY CHAIN MODELING OF ADDITIVELY MANUFACTURED VERSUS CNC-PRODUCED SPARE PARTS
(Mechanical Engineering, 2023 , Master Thesis)
This research proposes a generic BLOC-ICE-based framework that considers multiple aspects of the adoption of additive manufacturing (AM) in the spare part supply chain. It proposes also a multi-period multiple parts ...
MECHANICAL RESPONSE OF APPLYING DIFFERENT PARAMETERS ON NEGATIVE STIFFNESS HONEYCOMB STRUCTURE
(Mechanical Engineering, 2023 , Master Thesis)
It has become apparent that negative stiffness behavior may have potential applications in vibration isolation mechanisms, vibro-acoustic dampening materials, and mechanical switches. Unlike traditional honeycombs, due to ...
TOWARDS AN EFFICIENT HEALTH CONDITION MONITORING STRATEGY APPLIED FOR GEARING MECHANICAL SYSTEMS
(Mechanical Engineering, 2023 , Master Thesis)
Cracked teeth are a common phenomenon for gears. The dynamic behavior of gears in the presence of cracks and poor lubrication conditions that lead to rubbing between teeth are not well understood, which limits the development ...
A HYBRID NONLINEAR VIBRATION ENERGY HARVESTER FOR REMOTE SENSING APPLICATIONS
(Mechanical Engineering, 2023 , Master Thesis)
Energy harvesting mechanisms can be used to extract energy from ambient surroundings to power small electronic devices which has a significant advantage in realizing self-sustaining wireless devices. The piezoelectric ...
ENERGY ABSORPTION CAPABILITIES OF THIN-WALLED MULTI-CELL CORRUGATED TAPERED TUBES UNDER AXIAL AND OBLIQUE IMPACT LOADING CONDITIONS
(Mechanical Engineering, 2023 , Master Thesis)
Progressive collapse behavior, high energy absorption, low manufacturing cost, and lightweight made the thin-walled structures a great safety device in the automotive industry for crash energy absorption. In this thesis, ...
THERMAL COMFORT CONDITIONS OF AN INDOOR SWIMMING POOL
(Mechanical Engineering, 2023 , Master Thesis)
In this thesis, the thermal comfort and indoor conditions for an indoor swimming pool located in desert climate are investigated numerically. Such climate is characterized by very mild winters, and very hot and sunny summers ...
DEVELOPMENT AND EVALUATION OF A WIRELESS ACTIVE NOISE CONTROL SYSTEM IN AN ENCLOSED ENVIRONMENT
(Mechanical Engineering, 2023 , Master Thesis)
Active noise control (ANC) is a method used to reduce acoustical vibrations mainly within the low-frequency range. This thesis aims to implement a wireless active noise control system in an enclosed environment, evaluate ...
A HYBRID MAGNETORHEOLOGICAL ELASTOMER FOR SEMI-ACTIVE ISOLATION OF LONGITUDINAL AND TORSIONAL VIBRATIONS
(Mechanical Engineering, 2023 , Master Thesis)
Magnetorheological elastomers (MREs) are materials that exhibit a change in their mechanical properties, such as stiffness and damping, in response to an applied magnetic field. In general, MREs consist of an elastomeric ...
