摘要：

Currently, the bulk viscosity mu(b) of a gas can only be obtained with an acoustic absorption experiment. A method is proposed that is primarily applicable to a dense polyatomic gas. In this circumstance, the density-based thickness Lambda(p) is large, consisting of many thousands of mean-free paths. Moreover, the ratio mu b/mu (mu is the shear viscosity) is linear with this thickness. Consequently, shock measurements of Lambda(p) can be used to evaluate mu(b). The approach is illustrated using sulfur hexaflouride.
