Sensitivity analysis for piezoelectric energy harvester and bluff body design toward underwater pipeline monitoring
Qureshi , Fassahat Ullah Qureshi; Muhtaroglu, Ali; Tuncay, Kağan (2017-01-01)
Monitoring of underwater pipelines through wireless sensor nodes (WSNs) is an important area of research especially for locations such as underground or underwater pipelines, where it is costly to replace batteries. In this study, a finite element sensitivity and comparative analysis for piezoelectric (PZT) energy harvester operating in a fluid flow is done to power underwater in-pipe WSNs. Two types of bluff bodies D and I-shaped are used for comparison. Finite element simulations results show that PZT ene...
Sensitivity improvement strategies and applications for flexible and wearable capacitive pressure sensors
Çiçek, Melih Ögeday; Ünalan, Hüsnü Emrah; Çınar, Simge; Department of Metallurgical and Materials Engineering (2022-8)
Pressure sensors have attracted great interest in parallel with developments in wearable electronics, robotics, human-machine interface devices, and electronic skin. In this field, capacitive pressure sensors are gaining increasing research attention due to their high sensitivity, high stability, fast response/recovery times, and simple manufacturing routes. While capacitive pressure sensors have prominent features, there is still a long way to go before they become more common in wearable technology. Incre...
Sensitivity Analysis of Distortion of Carburized Steel Shafts Using Computer Simulations
Yazır, Büşra; Evcil, Elif; Yıldız, Seçil; Davut, Kemal; Şimşir, Caner (null; 2016-12-01)
Carburizing and subsequent quenching heat treatments are commonly used industrial processes to improve the properties and performance of steel shafts. Undesired dimensional and shape changes (distortion) related to these treatments are still the most frequent reason for expensive and time consuming corrective operations, low performance during service and even product rejection. The major aim of this study is to identify the suitable control parameters for subsequent optimization of the carburized quenching...

Sensitivity Analysis of Major Drilling Parameters on Cuttings Transport during Drilling Highly-inclined Wells
Ozbayoglu, E. M.; Miska, S. Z.; Takach, N.; Reed, T. (Informa UK Limited, 2009-01-01)
In this study, a layered cuttings transport model is developed for high-angle and horizontal wells, which can be used for incompressible non-Newtonian fluids as well as compressible non-Newtonian fluids (i.e., foams). The effects of major drilling parameters, such as flow rate, rate of penetration, fluid density, viscosity, gas ratio, cuttings size, cuttings density, wellbore inclination and eccentricity of the drillsting on cuttings transport efficiency are analyzed. The major findings from this study are,...
