Study of the effect of non-spherical particle on drag force was carried out by using numerical simulation. At Re<100
the flow over three different non-spherical particles (cube
cylinder and frustum) was calculated with N-S equations. In particular
three promising correlations for the drag coefficient of non-spherical particle were critically examined with the computational results. The best method appeared to be that of Ganser which used the equal volume sphere diameter and the sphericity of particle. Comparing the results obtained by two different cylinders arrangements
the axis of cylinder perpendicular to the coming flow direction and parallel to that
the divergence between these two cases was very obvious.
