Passive control of suddenly expanded flow and temperature distribution along the duct at the critical Mach number

Abrupt relief at the blunt base is common in aerospace because a recirculation zone reduces pressure and increases drag. This study investigates the control of base pressure at Mach 1.0 by using quarter-ribs placed at various points within an axisymmetric duct. CFD simulations with ANSYS Fluent iden...
