Abstract
Experiments have been performed to assess the base and total drag13; reduction due to a forward splitter plate (FSP) on two wedge models13; having semi-apex angle of 12 and 30 deg.13; Two splitter plates13; having a length of H and 3.2H (where H represents the base height)13; respectively were used.13; The13; Reynolds number of 4 x 1.0 and13; tests were made at a subcritical13; the wake survey method was utilised13; tQ determine the total drag. The results show virtually no change13; in base pressure due to FSP on both the models. The total drag on13; the other hand was about 9 and 4% lower for the 30 and 12 deg.13; wedges respectively for the optimum splitter plate.length equal to13; the base height. It is suggested that the observed drag reduction13; is due to lower -surface pressures associated with separated flow13; in the nose region.
