摘要：

This paper presents a new method for measuring water bulk viscosity directly by using stimulated Brillouin scattering (SBS). The relationships among shear viscosity, bulk viscosity, thermal capacity, and the line-width were deduced theoretically. The line-width and the bulk viscosity in water with different temperatures were investigated experimentally, and the error of experimental result was analyzed. The results obtained demonstrate that the proposed way is an accurate method for measuring bulk viscosity of water. (C) 2012 Elsevier B.V. All rights reserved.
