In ANSYS-FLUENT v.12 a new particle type is considered that is massless particle,My question is if we choose this type(massless particle) drag force(In general equation of motion of particle)is exerted on particle or no?drag term is a important part in equation of motion of particle.(Equation (15.2-1) of ANSYS-FLUENT 12 manual)

Massless particle type ihashas no associated physical properties, and no force is exerted on it. It is no force on continuous phase,and its motion follows with continuous phase.If in your model,discrete phase effects continuous phase's motion,you should choose other particle type.
