Modelling phase change with dissipative particle dynamics using a consistent boundary condition

With the introduction of an energy-conserving dissipative particle dynamics (DPD) scheme, simulations of the thermal behaviour of complex fluids at hy drodynamic time scales became possible. In this paper it is demonstrated th at a different equation of state allows us to perform simulations of the ph ase change of materials. We indicate that thermal simulations with a consta nt temperature boundary condition are only possible in an accurate way at h igh overlapping coefficients, if a newly developed consistent boundary cond ition is used.
