    Abstract

    Experiments have been performed to investigate the effectiveness of vortex generators on a hull body and a catamaran configuration. Forces measurements using a three component balance were conducted to measure lift and drag for a range of angles of drift from 0 degree to 20 degrees. The flow fields generated from both configurations were studied in a water flume using ink flow visualization and wave pattern analysis to determine the location of separation to aid the choice of vortex generators. It was shown that the effectiveness of the vortex generators depends on their size, shape, and distribution pattern on the body surface. The experiments demonstrated that vortex generators can be effective means of delaying boundary layer separation, reducing drag and increasing lift on the hull and catamaran body.
