The effect of subgrid scales on the dispersion of heavy particles could be significant especially when the subgrid energy content is not negligible and/or the particle time constant is small. In this work, a modified Langevin type equation is used to reconstruct the instantaneous velocity of the seen fluid particle which is needed in the particle momentum equation. To assess the model, a decaying isotropic turbulence is studied via

a priori

test. A good agreement between the model and DNS results is observed.
