摘要: In the original work by Burnett, pressure tensor and heat current contain two time derivates. Those are commonly replaced spatial derivatives using equations to zero order in Knudsen number. The resulting conventional Burnett were shown Bobylev be linearly unstable. this paper it is that of have a singularity. A hybrid constructed stable. It contains parameters, which larger than or equal some limit values. For any choice agree with each other second Kn, is, accuracy equations. simplest parameters no third derivative temperature, but inertia term derivatives. stationary flow, when terms Kn2Ma2 can neglected, only difference from Burne...
