Experimental Assessment of Bend-Twist Coupling Potentials of Composite Materials via Digital Image Correlation Method

Experimental Evaluation of Spin Echo based Magnetic Resonance Magnetohydrodynamic Flow Velocimetry Şişman, Mert; Sadighi, Mehdi; Eroğlu, Hasan Hüseyin; Eyüboğlu, Behçet Murat (2021-05-15) Magnetohydrodynamc (MHD) flow occurs due to the Lorentz force formed by the nteracton between the statc magnetc feld of the MR scanner andthe externally njected electrc current. The MR based magng of MHD flow has become a research feld of nterest recently. The MHD flow can beextracted from the MR phase mages obtaned usng a pulse sequence wth flow-encodng gradents. In ths study, the MHD flow dstrbutons of asmulated model and a homogeneous expermental phantom are obtaned. The MHD velocty contrast mages recons...

Experimental characterization of collapse-mode CMUT operation Oralkan, Omer; Bayram, Barış; Yaralioglu, Goksen G.; Ergun, A. Sanli; Kupnik, Mario; Yeh, David T.; Wygant, Ira O.; Khuri-Yakub, Butrus T. (2006-08-01) This paper reports on the experimental characterization of collapse-mode operation of capacitive micromachined ultrasonic transducers (CMUTs). CMUTs are conventionally operated by applying a direct current (DC) bias voltage less than the collapse voltage of the membrane, so that the membrane is deflected toward the bottom electrode. In the conventional regime, there is no contact between the membrane and the substrate; the maximum alternating current (AC) displacement occurs at the center of the membrane. I...
Experimental Determination of the Absorption Cross-Section and Molar Extinction Coefficient of Colloidal CdSe Nanoplatelets Yeltik, Aydan; Delikanli, Savas; Olutas, Murat; Keleştemur, Yusuf; Guzelturk, Burak; Demir, Hilmi Volkan (2015-11-01) There has been a strong interest in solution-processed two-dimensional nanomaterials because of their great potential in optoelectronics. Here, the absorption cross-section and molar extinction coefficient of four and five monolayer thick colloidal CdSe nanoplatelets (NPLs) having various lateral sizes are reported. The absorption cross-section of these NPLs and their corresponding molar extinction coefficients are found to strongly depend on the lateral area. An excellent agreement is observed between the ...
Experimental investigation of drag reduction effects of polymer additives on turbulent pipe flow using ultrasound Doppler velocimetry Zeybek Vural, Serife; Bayram, Göknur; Uludağ, Yusuf (The Scientific and Technological Research Council of Turkey, 2014-01-01) Drag reduction in fully developed turbulent pipe flow with 4 concentrations (200 to 500 wppm or mg/kg) of low molecular weight sodium carboxymethylcellulose (CMC) in aqueous solutions was investigated experimentally. Drag reduction was determined by pressure drop measurements. Maximum drag reduction achieved was 22% using 500 wppm CMC solution. To observe the impact of the presence of CMC on the flow, ultrasound Doppler velocimetry (UDV) was employed to monitor the instantaneous velocity distributions. Expe...
