Thermodynamically consistent fluid particle model for viscoelastic flows.
Phys Rev E Stat Nonlin Soft Matter Phys 2003; 68(4 Pt 1):041504PR

Abstract

A recently proposed viscoelastic dissipative particle dynamics model is put into a thermodynamically consistent form that allows for nonisothermal situations. This model consists of fluid particles that have an additional elastic vector characterizing the state of elongation of the molecules within the fluid particle. Very simple physical mechanisms are proposed for the dynamics of the elastic vector that, with the help of the GENERIC formalism, allows us to derive the full set of dynamic equations for the model. The model is further generalized to include polymer diffusion. The connection of the present model with the CONNFFESSIT approach and the Brownian configuration field approach is discussed.
