What is the basis for the effective radius not being equal to the physical radius when using IBM for solving fluid-particle interactions?

For fluid particle interations, specially sedimentation problems, when I am using the direct forcing immersed boundary method, the calculation of the torque is not exactly accurate. I have read in...

For direct forcing immersed boundary lattice boltzmann method, how to calculate the density at the Lagrangian nodes while calculating the force?

During the force calculation at the Lagrangian nodes using the formula F=2(rho)(Ud-Unof)/(dt) the non-forced velocity (Unof) is interpolated from the surrounding fluid domain (both inside and...
