"Simulation of lambda-phage DNA in microchannels using Dissipative Particle Dynamics"

Vasileios Symeonidis, George Em Karniadakis and Bruce Caswell




Abstract: Dissipative Particle Dynamics (DPD) is a simulation method at mesoscopic scales that bridges the gap between molecular dynamics and continuum hydrodynamics. It can simulate efficiently complex liquids and dense suspensions using only a few thousands of virtual particles and at speed-up factors of more than one hundred thousands compared to Molecular Dynamics. Lowe's approach provides a powerful alternative to the usual DPD integrating schemes. Here we demonstrate the details and potential of Lowe's scheme. We compute viscosity, diffusivity and Schmidt number values and we present comparison of wormlike chain models under shear with experimental and Brownian Dynamics results for lambda-phage DNA.
