A new thermodynamically consistent dissipative particle dynamics model accounts for nonisothermal conditions and molecular elongation. This advanced model incorporates polymer diffusion and connects with existing simulation approaches.

Area of Science:

  • Computational physics
  • Rheology
  • Polymer physics

Background:

  • Dissipative particle dynamics (DPD) is a mesoscopic simulation method.
  • Existing DPD models often lack thermodynamic consistency, especially for nonisothermal systems.
  • Modeling molecular elongation and polymer diffusion within DPD requires advanced formulations.

Purpose of the Study:

  • To develop a thermodynamically consistent viscoelastic dissipative particle dynamics (DPD) model.
  • To enable simulations under nonisothermal conditions.
  • To incorporate polymer diffusion and molecular elongation effects.

Main Methods:

  • Extension of the DPD model with an elastic vector for molecular elongation.
  • Application of the GENERIC (General Equation for Non-Equilibrium Reversible-Irreversible Coupling) formalism.
