The effect of the cylinder being turned counter-clockwise inside the dead zone at different positions near its base to adjust base pressure for varying levels of expansion for area ratio 9 has been investigated experimentally. When viewed from the top, a 2 mm diameter cylinder moving counter-clockwise is placed...

An experimental examination of the efficiency of a static cylinder to reduce base drag for over-expanded, perfectly-expanded, and under-expanded supersonic jets at Mach 2 is presented. As a passive control device, a 2 mm diameter static cylinder is positioned 2 mm from the square duct sidewall and 8 mm...
