We use the HD version of the ZEUS3D code to in investigate the dynamical evolution of media which are subject to a thermal instability (hereafter TI). Our simulations are parametrized essentially in term of the cooling timescale normalized to the dynamical timescale eta = (tcool / tdyn). TI is found to be efficient only for a given range of the eta parameter, namely 0.4 < eta < 2. On the global scale of our simulation box (1 Kpc**3), no excess of kinetic energy is observed, when compared to a non-cooling adiabatic model. However, whenever TI is relevant, kinetic energy excesses are observed on small lenghtscales. Further investigations of the phenomenon with higher resolution calculations and including self-gravity are in progress.
