Where, for no turbulence, Sij is the deviatoric stress tensor and is the deviatoric strain tensor.
with and E being the internal energy unit reference volume.
and with being the perfect gas constant.
and with c being the sound speed.
and
and then:
If P = cst = 0, then l=; so Where, is the dilatation coefficient, means dilatation, and in this case the parameters C2 and C3 will not be taken into account.
