  In the present paper we study the influence of second viscosity on
non-modally induced heating mechanism. For this purpose we study the set of
equations governing the hydrodynamic system. In particular, we consider the
Navier Stokes equation, the continuity equation and the equation of state,
linearise them and analyse in the context of non-modal instabilities. Unlike
previous studies in the Navier Stokes equation we include the contribution of
compressibility, thus the second viscosity. By analysing several typical cases
we show that under certain conditions the second viscosity might significantly
change efficiency of the mechanism of heating.
