Effect of Blow Suction Combined Jet Device on Maneuverability of Underwater Vehicle-Numerical Investigation
To improve the maneuverability of underwater vehicles the blow suction combined jet(BSCJ)device is adopted into the design of traditional controlling surfaces.The orthogonal design method was adopted to optimize the jet flow rate,and the suction/blow point and optimal combination parameters were obtained.The RANS solver was utilized to evaluate the hydrodynamic performance of an underwater vehicle with the BSCJ device.The effect of the BSCJ device on improving maneuverability was verified by comparing it with the traditional underwater vehicle.The internal flow mechanism was analyzed from vortex structures and pressure/velocity contour maps.The research results can provide theoretical guidance for applying the BSCJ method to underwater vehicles.
