Upper Bound for the Entropy Production and Dissipative Particle Dynamics

The upper bound for the entropy production of a dense gas is presented and its connection with the so-called Fisher information measure is revised. The relation with dissipative particle dynamics is analyzed, which serve to identify the thermostat for the fluid system. The analogy with a turbulence approach, a probabilistic approach to dynamical sytems, detailed balance for dissipative particle dynamics and fluctuation dissipation theorems for relaxing systems is presented.
