INTERFERENCE EFFECTS ON THE PRESSURE DISTRIBUTION ON THE GROUND PLANEAROUND A LOW-RISE AND A TALL BODY IN TANDEM ARRANGEMENT

In this paper, the pressure distribution and how visualisation on the ground plane around a low-rise prismatic body with height to width rat io (h/b) of 1 and a tail body (h/b = 5) in tandem arrangement are pres ented. Two cases are considered: (i) when the shorter body is in front and the tall body at the lear, (ii) when the tall body is in front an d the short one at the rear. In each case the gap between the two is s ystematically varied. The results indicate that in both cases it is th e tall body which controls the pressure and the how held and due to th e resulting interference effects very severe how conditions can be exp ected around the low-rise body.
