Effective Viscosities of Smoothed Dissipative Particle Dynamics in 3D
We aim to extend simpler stochastic models for turbulence such as generalized Langevin model [1, 2]. In this work, a particular focus is placed on the Smoothed Dissipative Particle Dynamic (SDPD) model. It is the combination of the meshless Lagrangian discretization of the Navier–Stokes equations (smoothed particle hydrodynamics, SPH) and additional thermal fluctuations. SDPD satisfies the fluctuation-dissipation theorem.
