Maneuvering hydrodynamics of fish and small underwater vehicles.
The understanding of fish maneuvering and its application to underwater rigid bodies are considered. The goal is to gain insight into stealth. The recent progress made in NUWC is reviewed. Fish morphology suggests that control fins for maneuverability have unique scalar relationships irrespective of their speed type. Maneuvering experiments are carried out with fish that are fast yet maneuverab...
متن کاملEllipsoidal flows in relativistic hydrodynamics of finite systems
A new class of 3D anisotropic analytic solutions of relativistic hydro-dynamics with constant pressure is found. We analyse, in particular, solutions corresponding to ellipsoidally symmetric expansion of finite systems into vacuum. They can be utilized for relativistic description of the system evolution in thermodynamic region near the softest point and at the final stage of the hydrodynamic e...
متن کاملSimple solutions of relativistic hydrodynamics for systems with ellipsoidal symmetry
Simple, self-similar, analytic solutions of (1+3)-dimensional relativistic hydrodynamics are presented for ellipsoidally symmetric finite fireballs corresponding to non-central collisions of heavy ions at relativistic bombarding energies. The hydrodynamical solutions are obtained for a new, general family of equations of state with the possibility of describing phase transitions.
متن کاملHydrodynamics of Coalescing Binary Neutron Stars: Ellipsoidal Treatment
We employ an approximate treatment of dissipative hydrodynamics in three dimensions to study the coalescence of binary neutron stars driven by the emission of gravitational waves. The stars are modeled as compressible ellipsoids obeying a polytropic equation of state; all internal fluid velocities are assumed to be linear functions of the coordinates. The hydrodynamic equations then reduce to a...
متن کاملAnalysis of Maneuvering Fish Fin Hydrodynamics Using an Immersed Boundary Method
A thorough understanding of the pectoral fin hydrodynamics of the bluegill sunfish (Lepomis macrochirus) provides insight that can be applied to the design of propulsors for autonomous underwater vehicles (AUVs). The pectoral fin represents a continuously deforming complex moving boundary problem. For the sunfish, both propulsion and maneuvering are entirely controlled by the pectoral fins. Fir...
