Nine research teams organized a round-robin measurement campaign of the wake of two porous discs in a homogeneous and "low-turbulent' flow. Mean streamwise velocity and turbulence intensity profiles at four diameters downstream of the discs were measured and compared through such metrics as the maximum of velocity deficit, the maximum of turbulence intensity, the wake width and the thrust coefficient. The dependence of these metrics on the inflow conditions (freestream turbulence intensity and Reynolds number based on the disc diameter) is discussed.

Formability analysis of sheet metals by cruciform testing Güler, Baran; Alkan, K.; Efe, Mert (2017-07-06) Cruciform biaxial tests are increasingly becoming popular for testing the formability of sheet metals as they achieve frictionless, in-plane, multi-axial stress states with a single sample geometry. However, premature fracture of the samples during testing prevents large strain deformation necessary for the formability analysis. In this work, we introduce a miniature cruciform sample design (few mm test region) and a test setup to achieve centre fracture and large uniform strains. With its excellent surface...
Thermally Stimulated Current Study of Shallow Traps in As-Grown TlInSe2 Chain Crystals Hasanlı, Nızamı (Institute of Physics, Polish Academy of Sciences, 2011-03-01) Thermally stimulated current measurements were carried out on as-grown TlInSe2 single crystals. The investigations were performed in temperatures ranging from 10 to 260 K with heating rate of 0.3 K s(-1). The analysis of the data revealed the hole traps levels located at 6 and 57 meV. The activation energies of the traps have been determined using various methods of analysis, and they agree with each other. The concentration (2.8 x 10(13) and 3.4 x 10(12) cm(-3)) and capture cross section (4.1 x 10(-28) and...
Measurement of associated production of vector bosons and top quark-antiquark pairs in pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (American Physical Society (APS), 2013-04-01) The first measurement of vector-boson production associated with a top quark-antiquark pair in proton-proton collisions at root s = 7 TeV is presented. The results are based on a data set corresponding to an integrated luminosity of 5.0 fb(-1), recorded by the CMS detector at the LHC in 2011. The measurement is performed in two independent channels through a trilepton analysis of t (t) over barZ events and a same-sign dilepton analysis of t (t) over barV (V = W or Z) events. In the trilepton channel a direc...
Final results of the search for nu(mu) to nu(tau) oscillations by CHORUS Güler, Ali Murat (2005-09-14) The final CHORUS results of the search for tau-lepton decays and the analysis of the final statistics in terms of νµ - ντ oscillation will be presented.
Calculation of the Raman frequencies of lattice modes in the disordered phase II of NH4Br at high pressures Yurtseven, Hasan Hamit (Physics Essays Publication, 2010-01-01) The Raman frequencies are calculated here at various temperatures for the nu(7) (56 cm(-1)) and nu(5) (134 cm(-1)) lattice modes in the disordered phase II of NH4Br. The lattice parameter data obtained at zero pressure are used to calculate the Raman frequencies of those modes studied for constant pressures of 0.1, 108, and 637.5 MPa in phase II of the NH4Br crystal. Through the mode Gruumlneisen parameter which is kept constant in the disordered phase II, the Raman frequencies calculated decrease linearly ...
