On an acoustic method for complex viscosity measurement
Abstract
Investigation of the possibility of using electroacoustic signals in a Powell-Evring-type fluid for determining the non-Newtonian coefficients for such a fluid. It is shown that experimentally determined data on the acoustic properties of a viscoelastic fluid can be used to evaluate its complex viscosity.
