This paper presents measurements of the mechanical loads that splitter fairings on vertical and inclined risers will experience while in the wave zone or due to current drag. A 21″ pipe was utilized for the measurements, which corresponds to prototype size for a production riser and a 1:2.5 ...
A light reflection technique is used to measure quantitatively the surface elevation of Faraday waves. The performed measurements cover a wide parameter range of driving frequencies and sample viscosities. In the capillary wave regime the bifurcation diagrams exhibit a frequency independent scaling proportio...
In this paper, aircraft measurements are presented of liquid phase (ice-free) wave clouds made at temperatures greater than ???5掳C that formed over Scotland, UK. The horizontal variations of the vertical velocity across wave clouds display a distinct pattern. The maximum updraughts occur at ...
"Wave spectra were measured along a profile extending 160 kilometers into the North Sea westward from Sylt for a period often weeks in 1968 and 1969. During the main experiment in July 1969, thirteen wave stations were in operation, of which six stations continued measurements into the first ...
In this letter, measurements and simulations of wave propagation inside a jet engine fan have been performed. The investigation was done using both EM simulations of different cases of propagation inside the engine and by measuring the corresponding cases inside a half-scale model of a jet engine...
By combining two-frequency backscatter resonance intensity with estimates of the directional wave spectrum (obtained by the airborne surface contour radar) and the known radar beam geometry, it was possible to solve for the unknown MTF using a system equation that has been verified in previous ...
A compact tension specimen is fabricated and the amplitude of the transmitted wave is analyzed as a function of position along the fatigued crack surface. In order to measure as many nonlinear harmonic components as possible, broadband lithium niobate (LiNbO) transducers are employed together with a...
The submillimeter wave spectrum of 32S16O2, 32S16O2(ν2), and 34S16O2 Extensive new measurements in the region 400–1000 GHz have been made on 32S 16O 2, 32S 16O 2( ν 2), and 34S 16O 2. These measurements represent almost a threefold extension in the frequency region for which...
We describe what we believe to be the first wave-front measurements of the human eye at a sampling rate of 300 Hz with a custom Hartmann-Shack wave-front sensor that uses complementary metal-oxide semiconductor (CMOS) technology. This sensor has been developed to replace standard charge-coupled...
The pressure front that appears at its site represents an ultrasonic shock wave spreading into surrounding water. At the same time the cavitation bubble develops. The effect of both is particularly important in ocular microsurgery, where Q-switched lasers are used to vaporize the tissue in ...
