High-speed visualization of acoustically excited cavitation bubbles in a cluster near a rigid boundary
(Springer Berlin Heidelberg, 2017)
In the present work, high-speed visualizations at one million frames/s have been used to study the oscillation characteristics of acoustic cavitation bubbles. The bubbles are generated by acoustic cavitation using an ...
Effect of purity levels on the high-temperature deformation characteristics of severely deformed titanium
(Springer International Publishing, 2017)
In the present investigation, high-temperature compression tests were conducted at strain rates of 0.001 to 0.1 s−1 and at temperatures of 873 K to 1173 K (600 °C to 900 °C) in order to study the hot deformation characteristics ...
Characterization of nano-scale protective oxide films: application on metal chemical mechanical planarization
(The Electrochemical Society, 2015)
This study focuses on the characterization of nano-scale metal oxide films for chemical mechanical planarization (CMP) applications. The protective nature of the self-grown metal oxide layers in the CMP slurry environment ...
A Complete procedure for predicting and improving the performance of HAWT's
(IOP Publishing, 2014)
A complete procedure for predicting and improving the performance of the horizontal axis wind turbine (HAWT) has been developed. The first process is predicting the power extracted by the turbine and the derived rotor ...
Needle localization using gabor filtering in 2D ultrasound images
(IEEE, 2014)
In the percutaneous needle procedures using ultrasound (US) imaging, the needle should be detected precisely to avoid damage to the tissue and to get the samples from the appropriate site. Excessive artifacts and low ...
A torque matched aerodynamic performance analysis method for the horizontal axis wind turbines
(Wiley, 2013-11)
An analysis method is developed to test the operational performance of a horizontal axis wind turbines. The rotor is constrained to the torque–speed characteristic of the coupled generator. Therefore, the operational ...
Heat transfer characteristics of impinging steady and synthetic jets over vertical flat surface
(Elsevier, 2015-01)
In this paper, heat transfer characteristics of single-slot impinging steady and synthetic jets on a 25.4-mm × 25.4-mm vertical surface were experimentally investigated. The experiments were conducted with a fixed nozzle ...
Coexistence of multiple regimes for near-field thermal radiation between two layers supporting surface phonon polaritons in the infrared
(American Physical Society, 2011)
We demonstrate the coexistence of different near-field thermal radiation regimes between two layers supporting surface phonon polaritons (SPhPs) in the infrared. These regimes existwhen the distance of separation between ...
Self-cleaning ability quantization of textiles with degussa P-25
(Trans Tech Publications Inc., 2018)
This study proposes a systematic quantification of effectiveness of the Degussa P-25 titania particles used as a benchmark in photocatalytic applications to standardize ability of self-cleaning textile applications and to ...
The effect of nanoparticle type and nanoparticle mass fraction on heat transfer enhancement in pool boiling
(Elsevier, 2017-06)
Determining the heat transfer performance with nanofluids is of cardinal importance in the utilization of nanofluids in thermal systems. This study presents an experimental investigation on nucleate pool boiling heat ...
