Taken together, the results show that SAS computations can accurately reproduce frequency and amplitude of thermoacoustic oscillations of turbulent partially premixed flames in a gas turbine combustor provided that proper modeling of fuel supply and acoustic boundary conditions is applied.
For other models which also reproduce frequency dependence or multiple-spike protocol results, see Abarbanel et al. (2002), Senn (2002) and Appleby and Elliott (2005).
They use 9mm drivers to reproduce frequencies from 6 – 23,000 Hz and come with small, medium, or large earbuds.
The bass cabinet is made of mahogany and features a 4-inch cone woofer for the lows and a one-inch ring-drive tweeter that can reproduce frequencies up to 100 kHz.
Aside from the beautiful horns, one of the most unique features of the Spharon Excalibur's are the horn loaded Plasma Ion Tweeters that allow the speakers to reproduce frequencies up to 50kHz.
The crossover section may also include a high-pass "infrasonic" filter which prevents the subwoofer driver from attempting to reproduce frequencies below its safe capabilities.
Transgenic mice had shiny fur indicative of good general health, and reproduced with frequency and litter sizes comparable to wild-type mice (data not shown).
For random directionally spread waves, the wavemaker reproduced input frequency-dependent and bulk mean wave angle and directional spread to within 4° at Ur < 0.12.
We also checked the power spectra of the simulated LFPs to make sure the Bush model populations reproduced similar frequency-scaling properties to the Mainen cell populations.
It is shown analytically that the present simulation scheme suppresses high frequency electromagnetic waves and that it accurately reproduces low frequency waves in the plasma.
