A comparison of the effect of single and multiple cavities on base flows

The paper represents a novel approach to understand the effect of single and multiple cavities on base pressure. We considered a control plate of 1 mm thick between a square nozzle of the cross-sectional area of 100 mm 2 and square duct of the cross-sectional area of 625 mm 2 . Both single and multi...
