Rayleigh-Brillouin light scattering spectroscopy of air; experiment, predictive model and dimensionless scaling
Yuanqing Wang, Ziyu Gu, Kun Liang +1
Spontaneous Rayleigh-Brillouin scattering (RBS) experiments have been performed in air for pressures in the range 0.25 - 3 bar and temperatures in the range 273 - 333 K. The functi…
Rayleigh-Brillouin Scattering in Binary Gas Mixtures
Ziyu Gu, Wim Ubachs, Willem van de Water +1
Precise measurements are performed on spectral lineshapes of spontaneous Rayleigh-Brillouin scattering in mixtures of the noble gases Ar and Kr, with He. Admixture of a light He at…
A systematic study of Rayleigh-Brillouin scattering in air, N2 and O2 gases
Ziyu Gu, Wim Ubachs
Spontaneous Rayleigh-Brillouin scattering experiments in air, N2 and O2 have been performed for a wide range of temperatures and pressures at a wavelength of 403 nm and at a 90 deg…
Rayleigh-Brillouin scattering of carbon dioxide
Ziyu Gu, Wim Ubachs, Willem van de Water
The spectral lineshape of spontaneous Rayleigh-Brillouin scattering in CO2 is studied in a range of pressures. The spectrum is influenced by the bulk viscosity, which is a relaxati…
Rayleigh-Brillouin scattering profiles of air at different temperatures and pressures
Ziyu Gu, Benjamin Witschas, Willem van de Water +1
Rayleigh Brillouin (RB) scattering profiles for air have been recorded for the temperature range from 255 to 340 K and the pressure range from 640 to 3300 mbar, covering the condit…
Temperature-dependent bulk viscosity of nitrogen gas determined from spontaneous Rayleigh-Brillouin scattering
Ziyu Gu, Wim Ubachs
Values for the bulk viscosity of molecular nitrogen gas (N2) were derived from spontaneous Rayleigh-Brillouin (RB) scattering at ultraviolet wavelengths (366.8 nm) and at a 90 degr…
A Rayleigh-Brillouin scattering spectrometer for ultraviolet wavelengths
Ziyu Gu, M. Ofelia Vieitez, Eric-Jan van Duijn +1
A spectrometer for the measurement of spontaneous Rayleigh-Brillouin scattering line profiles at ultraviolet wavelengths from gas phase molecules has been developed, employing a hi…
