The Optimum Shaping of Axisymmetric Bodies for Minimum Drag in Incompressible Flow
PURDUE UNIV LAFAYETTE IN AUTOMATIC CONTROL CENTER
Pagination or Media Count:
The hydrodynamic problem is the design of submerged minimum drag axisymmetric vehicles for a specified enclosed volume and constant speed. Drag is to be minimized. Drag reduction is to be accomplished solely through manipulation of the vehicle shape other means of drag reduction, such as polymer injection into the boundary layer, are not considered. A drag model, valid for nonseparating flows, consists of computer programs available in the literature, representative of state-of-the-art drag prediction methods.
