主 题:submarine Detached Eddy Simulation (DES) method vortex control baffler horseshoe vortex attached vortex wind tunnel experiment
摘 要:The horseshoe vortex generated around the sail-body junction of a submarine has an important influence on the uniformity of the submarine wake at the propeller *** this article,the horseshoe vortex is simulated by the Detached Eddy Simulation(DES) method,and a new method to control the horseshoe vortex by vortex control baffler is *** numerical simulation shows that a kind of attached vortex,with the rotation direction opposite to that of horseshoe vortex,is generated by the vortex control *** the attached vortex,the strength of the horseshoe vortex is significantly *** wind tunnel experiment on a submarine model is carried out,and the axial velocities at the propeller disc of the submarine with and without vortex control baffler are measured by a hot wire anemometer *** is shown from the experimental results that the vortex control baffler can enhance the uniformity of the wake at the propeller disc,which helps to improve the propeller *** engineering applicability of the vortex control baffler is discussed.
