N2  - The  thesis  provides  a  novel  way  to  couple  vortices  in  the  downstream  of  an  immersed  solid body holding station within a moving steady laminar flow. A two dimensional stiff body with dimensions similar to Carangiform type fishes is assumed. An array of assumed tail inclinations is  utilized  to  model  fishes  flapping  its  tail.  A  stochastic  multivariate  framework  is  used  to predict the lift generated on  the body by coupling parameters effecting the body (shear stress, Re and tail inclination) to the circulationsin the wake and lateral regions. Shear stress is derived from the steady laminar flow simulations across the stationed body. Here the areas of the solid-bodily rotations or vortices besides the lateral and wake region of the body are quantified and measured  using  graphical  method.  The  lift  experienced  by  the  body  is  found  to  be  most influenced by the circulations irrespective of their tail inclinations. Thus, the lift experienced is self-propulsive.  For  bodies  with  downward  tail  inclinations,  shear  stress and  inclination provide  negative  influence  to  the  experienced  lift.  The  implication  is  to  understand  the  use  of minimum levels of this self-propulsive lift in aquatic manoeuvrability, solid waste management in surface water and design of under-water vehicles
