Impact of volume viscosity on a shock-hydrogen-bubble interaction

We investigate the influence of volume viscosity on a planar shock-hydrogen-bubble interaction. The numerical model is two dimensional and involves complex chemistry and detailed transport. All transport coefficients are evaluated using algorithms which provide accurate approximations rigourously derived from the kinetic theory of gases. Our numerical results show that volume viscosity has an important impact on the velocity distribution - through vorticity production - and therefore on the flame structure.
