The bending effect in turbulent flame propagation
… is investigated. The long-standing issue of the 'bending effect' is focused upon, which refers to the experimentally-observed inhibition of flame propagation velocity at high intensities of turbulence. Plausible mechanisms for the bending effect are investigated by isolating systematically the …

Thermo-Mechanical Behavior During Steel Continuous Casting in Funnel Molds
… funnel molds, with the goal of understanding the effect of funnel shape on the solidifying steel shell. The numerical models have been calibrated with plant measurements from the Corus Direct Sheet Plant in IJmuiden, The Netherlands, and are used to recommend funnel designs and narrow-face taper …

Design and characterisation of long period grating (LPG) - based optical fibre sensors for acoustic wave detection
… temperature, strain, refractive index and bending, therefore they have been explored widely for a range of potential sensing applications. This thesis is focused on the design, implementation and evaluation of LPGs for acoustic wave detection. In doing so, the LPG-based sensor has been …

Measurement of Surface and Interfacial Energies between Solid Materials Using an Elastica Loop
… results indicate that due to anticlastic bending, the contact first occurs at the edges of the loop, and then spreads across the width as the displacement continues to increase. The patterns observed show that the loop is eventually flattened in the contact region and the effect of …

Stress and stick-slip analyses for optical fiber pull-out and thin film peel tests
… slender beam theory is employed including bending and stretching. The stick-slip analysis is carried out for both the 90$\sp\circ$ peel test and the roller peel test. It is found that bending effect is in general so important that it cannot be neglected. For the 90$\sp\circ$ peel test, the …

Tensile creep of silicon carbide whisker-reinforced alumina composites
… resistance compared to pure alumina and the effect of increasing whisker volume fraction was significant up to 30%. Relatively high stress exponents were found, which is most probably associated with much enhanced cavitational creep in tension. The activation energy varied with whisker volume …

Multiphysics modeling of the steel continuous casting process
… hot face temperatures, which combined with the bending effect of the mold on the shell, can lead to longitudinal facial cracks. The shoulder region of the beam-blank mold shows a local hot spot that can be reduced with additional cooling in this region. The distorted shape of the funnel mold …

Atomic structures of carbon nanomaterials studied by coherent electron diffraction
… two different bond lengths in achiral due to the bending effect of the curvature of the CNTs. Furthermore, in-situ heating experiment of the same MWCNT shows large thermal contractions for all the walls of the MWCNT, and the coefficient of radial thermal contraction has strong diameter dependence. …

X-Ray studies of the physics of matter around super-massive black-holes in nearby Seyfert galaxies
… model. Moreover, the presence of a X-ray Baldwin effect in type I sources has been measured using for the first time the 20-100 keV luminosity (EW proportional to L(20-100)^(−0.22±0.05)). This finding suggests that the torus covering factor may be a function of source luminosity, thereby …
