Measurement of Bulk Viscosity of CO2 Based on Spontaneous Rayleigh-Brillouin Scattering

open access: yesIEEE Access, 2020
The spontaneous Rayleigh-Brillouin scattering spectra of CO2 are measured at different temperatures from 278 K to 369 K corresponding to the pressure range over 4-7 bar approximately and compared with the Tenti S6 model.
