Modeling of various heat transfer problems using dissipative particle dynamics

Dissipative particle dynamics with energy conservation (eDPD) was applied to conduction heat transfer in two-dimensional domains. The ability of the eDPD approach to simulate heat conduction in two-dimensional domains was tested by implementing various types of boundary conditions. The boundary conditions used in the present study are a combination of constant temperature, constant heat flux, adiabatic, and convective heat transfer. Furthermore, the eDPD approach was extended to study two-dimensional conduction with internal heat generation. This problem was further used to calculate the thermal diffusivity of the two-dimensional eDPD system. The eDPD simulations were compared to analytical and finite-difference solutions. The simulations show that the eDPD approach properly calculated the temperature distribution in the conduction domain.
