Modeling slender bodies with the method of regularized Stokeslets
The motion and flow generated by immersed structures in a fluid in the Stokes regime can be modeled with a variety of different numerical methods. The mathematical structure of the Stokes equations allows one to describe the flow around a three-dimensional object using only information regarding its geometry. This leads to computational techniques such as boundary integral methods or the method...
متن کاملHypersonic flow past slender bodies in dispersive hydrodynamics
The problem of two-dimensional steady hypersonic flow past a slender body is formulated for dispersive media. It is shown that for the hypersonic flow, the original 2+ 0 boundary-value problem is asymptotically equivalent to the 1+ 1 piston problem for the fully nonlinear flow in the same physical system, which allows one to take advantage of the analytic methods developed for one-dimensional s...
متن کاملOptical Detection of Transitional Phenomena on Slender Bodies in Hypervelocity Flow
Measurement of the phenomena associated with hypervelocity boundary layer transition requires the development of high-speed detection techniques. Two reasons for the current search for a reliable non-intrusive optical technique include: 1) high-enthalpy facilities suffer from a harsh environment in the test section after the test time, 2) optical diagnostics tend to achieve higher sampling rate...
متن کاملStability of Symmetric and Asymmetric Vortex Pairs over Slender Conical Wings and Bodies
Theoretical analyses are presented for the stability of symmetric and asymmetric vortex pairs over slender conical wings and bodies under small perturbations in an inviscid incompressible flow at high angles of attack and sideslip. The three-dimensional problem of a pair of vortices over slender conical wings and bodies is reduced to a problem in two dimensions by using the conical flow assumpt...
متن کاملStability of Vortex Pairs over Slender Conical Bodies: Analysis and Numerical Computation
A N INITIALLY symmetric vortex pair over a slender pointed body or wing–body combination, such as that shown in Fig. 1, becomes asymmetric as the angle of attack is increased beyond a certain value, causing large rolling moments in the case of swept wings or large side forces in the case of slender bodies, even at zero roll and yawing angles. At even larger angles of attack, unsteady vortex she...
