Numerical investigation of droplet motion and coalescence by an improved lattice Boltzmann model for phase transitions and multiphase flows

► An improved LBM multiphase model is proposed. ► A new scheme for the force term is proposed. ► We compared existing force incorporation methods and adopted EDM method. ► Our proposed model can give more accurate and stable numerical results. ► A high density ratio can be handled by our proposed mo...
