The dissipative particle dynamics mesoscopic simulation method is analyzed thoroughly by identifying the scaling factors necessary to simulate a multicomponent system. A new framework of general expressions is derived relating the parameters in the system to their dimensionless quantities. The consistent non‐dimensionalization used in this paper serves to connect the previous models in the literature. When the scaling factors are based on the solvent in a multicomponent system, the system of equations reduces to the well‐known Groot and Warren model. Validation results for ideal, simple and binary immiscible fluids are presented and compared with established results from the literature. The framework established herein is an important step toward the practical application of dissipative particle dynamics for the analysis of complex fluid systems.
