dc.description.abstractA series of experiments was carried out with two streamlined foils at two different speeds in a towing tank. The ambient turbulence (nearly isotropic) was generated by means of a biplanar grid. The model-grid separation distance was varied systematically in order to subject the trailing vortices to varying degrees of turbulence. The data have been expressed in terms of a normalized turbulence parameter and the relative rise of the vortices. The results have shown that the ultimate height to which the vortices rise prior to their demise is controlled by the two parameters cited, irrespective of the shape and the aspect ratio of the lifting surfaces. A numerical analysis has been initiated to analyze the motion of the trailing vortices and the propagation of internal waves in density stratified medium with the ultimate objective of incorporating the effect of turbulence into the numerical model.en_US
