(a) Schematic of pipe cross-section model in DPD. Red: wall particles; blue: fluid particle (only shows half of fluid particle). (b) Nondimensional density and velocity profile from DPD simulation (solid line) and analytical solution for velocity (diamond points). Simulation parameters are 𝑘𝑇=1.0, 𝑎_𝑓=25.0, 𝜌_𝑓=𝜌_𝑤=3.0, and 𝛾_𝑓=𝛾_𝑤=4.5.
