Investigation of corrosion behavior of carbon steel for petroleum pipeline applications under turbulent flow conditions
(Institute of Information Science, 2020)
This study investigates the corrosion of steel samples immersed in water with a dynamic corrosion setup at different pH values for three different velocities and three different exposure time. The characteristics of material ...
Evaluation of NaOH pre-treatment on the corrosion behavior and surface characteristics of hydroxyapatite coated NiTi alloy
(Springer Nature, 2020-08-02)
Successful short-term implementation of nickel-titanium (NiTi) alloys as implants has been a motivation for the development of long-term applications. However, rendering these as safe implant materials is challenging. The ...
An experimental and theoretical analysis of vapor-to-liquid phase change on microstructured surfaces
(Elsevier, 2020-09)
In this work, an experimental and a theoretical study was carried out on condensation heat transfer on vertically aligned bare unstructured, micro V-grooved and square-grooved copper substrates. During the experiments, ...
Investigation of the effect of particle stability on the transport properties and thermal behavior of ethylene glycol-water/SiO2 binary nanofluids
(IOP Publishing, 2020-04-09)
Nanofluids (Nfs) are considered as an effective working media in different thermal processes. Over the years, much attention has been paid to the problem of nanoparticle stability in base fluids in an unconfined area of ...
Design sensitivity and optimization of powertrain mount system design parameters for rigid body modes and kinetic energy distributions
(Springer Nature, 2020-08-24)
This study evaluates the influences of the powertrain mount design parameters on the frequencies of powertrain rigid body modes and their kinetic energy distributions (KEDs), which play an important role in the low-frequency ...
An integrated homogenization–based topology optimization via RBF mapping strategies for additively manufactured FGLS and its application to bandgap structures
(Springer Nature, 2020)
The manufacturing of lattice structures has been greatly facilitated thanks to the advances in additive manufacturing. Functionally graded lattice (FGL) structures, a major class of such structures, developed using topology ...
Simultaneous improvement in strength and ductility of severely deformed niobium alloy
(Elsevier, 2020-11-15)
The present study is on the improved monotonic response of a severely deformed niobium-based alloy. Nb-1Zr alloy was processed at room temperature using equal channel angular extrusion and cold rolling. After 16 passes, a ...
Modeling, transient simulations and parametric studies of parabolic trough collectors with thermal energy storage
(Elsevier, 2020-03-15)
For investigating the system response of parabolic trough collector heat generating system, a plant with parabolic trough collector field and two-tank molten salt thermal energy storage model with component-level control ...
Gabor filter-based localization of straight and curved needles in 2D ultrasound images
(TÜBİTAK, 2020)
2D ultrasound (US) is one of the most commonly used medical imaging devices for needle localization in biopsies. However, the produced images are low-resolution and contain an excessive number of artifacts, which makes the ...
Effect of polymer coating on vapor condensation heat transfer
(ASME, 2020-04-01)
Condensation heat transfer coefficients (HTCs) are rather low compared to thin film evaporation. Therefore, it can be a limiting factor for designing heat transfer equipment. In this work, heat transfer characteristics of ...
