Axial incompressible viscuous flow past as slender body of revolution

Energy Harvesting from Axial Flow Induced Instabilities in Slender Structures

In this work we examine the prospects for harvesting energy from flutter instabilities of a slender, flexible cylinder in an axial flow stream. We couple the fluid-solid model and include energy harvesting as curvature based damping. In the first instance we model the reduced order system comprising of an articulated rigid cylinder pair with discrete springs and dampers and demonstrate the scop...

Spatial dispersive shock waves generated in supersonic flow of Bose-Einstein condensate past slender body

Supersonic flow of Bose-Einstein condensate past macroscopic obstacles is studied theoretically. It is shown that in the case of large obstacles the Cherenkov cone transforms into a stationary spatial shock wave which consists of a number of spatial dark solitons. Analytical theory is developed for the case of obstacles having a form of a slender body. This theory explains qualitatively the pro...

Hypersonic 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...

Analytic Solution for Hypersonic Flow Past a Slender Elliptic Cone Using Second-Order Perturbation Approximations

An approximate analytical solution is obtained for hypersonic flow past a slender elliptic cone using second-order perturbation techniques in spherical coordinate systems. The analysis is based on perturbations of hypersonic flow past a circular cone aligned with the free stream, the perturbations stemming from the small cross-section eccentricity. By means of hypersonic approximations for the ...
