INTERFERENCE EFFECTS ON THE PRESSURE DISTRIBUTION ON THE GROUND PLANE AROUND 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 ratio (h/b) of 1 and a tail body (h/b = 5) in tandem arrangement are presented. 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 and the short one at the rear. In each case the gap between the two is systematically varied. The results indicate that in both cases it is the tall body which controls the pressure and the how held and due to the resulting interference effects very severe how conditions can be expected around the low-rise body.
