Evaluation of force implementation in pseudopotential-based multiphase lattice Boltzmann models

► We evaluated force implementation in pseudopotential-based multiphase LB models. ► Evaluation is done from aspects of force expression and its incorporation scheme. ► Force expression has greater impact on coexistent curves than the incorporation scheme. ► Both force expression and the incorporation scheme largely affect the spurious current. ► An additional term is added to capture density more precisely at low temperatures.
