Analysis of the Steady-Stream Active Flow Control for the Blended-Winged-Body Underwater Glider

The BWB-UG is a glider with smooth and integrated fuselage wing. Its lift-to-drag properties are some of the most significant factors affecting its performance. In order to improve hydrodynamic characteristics, method steady-stream active flow control (SS-AFC) proposed. computational fluid dynamics used numerically investigate SS-AFC BWB-UG. mechanism effect on characteristics revealed from field aspect. before after installing was simulated using FLUENT. results show that can effectively optimise structure around steady-suction AFC increase ratio by up 45.01%. With steady-jet AFC, be increased as much 93.17%.
