Study on Flow Field around Slender Diamond Cone Traveling at Hypersonic Speed.

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 ...

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...

Supersonic Combustion Flow Visualization at Hypersonic Flow

Currently, a new generation of scientific aerospace vehicles, using advanced hypersonic airbreathing propulsion based on supersonic combustion technology, is in development at several research centers [1]. The 14-X Brazilian Hypersonic Aerospace Vehicle, Figure 1, designed by Rolim et al. [2], at the Prof. Henry T. Nagamatsu Laboratory of Aerothermodynamics and Hypersonics, Figure 2, at the Ins...

A Review of Recent Studies on Simulations for Flow around High-Speed Trains

Fluid flow around bluff bodies occurs in numerous fields of science and engineering, such as flows pass vehicles, cables, towers and bridges. These flows have been studied experimentally and numerically for the last several decades. The investigation of flow around high-speed trains is an important application of bluff bodies. Fluid flow, aerodynamic forces and moments, separation and wake regi...
