چکیده

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 Institute for Advanced Studies (IEAv), is part of the continuing effort of the Department of Aerospace Science and Technology (DCTA), to develop a technological demonstrator using: i) ”waverider” technology to provide lift to the aerospace vehicle, and ii) ”scramjet” technology to provide hypersonic airbreathing propulsion system based on supersonic combustion.

Development of an Upwind Algorithm at Subsonic Regions in the Solution of PNS Equations

In this paper an upwind algorithm based on Roe’s scheme is presented for solution of PNS equations. Non iterative-implicit method using finite volume technique is used. The main advantage of this approach, in comparison with similar upwind methods, is reduction of oscillations around sonic line. This advantage causes the present method to be able to analyze supersonic flows with free stream Mac...

Chapter 5: Review of Experiments on Ignition and Flameholding in Supersonic Flow

5.1 ABSTRACT Supersonic combustion data obtained at the low static temperatures appropriate for an efficient scramjet engine are reviewed. Attention is directed at the methods by which the fuel was ignited and combustion maintained. The cited supersonic combustion experiments are grouped under the six headings: chemical intiators; non-uniform flows; turbulent flameholding; combustion induced co...

Numerical Analysis of Hypersonic Combustion without Cavity Based Injection with Finite Rate Chemistry Model

In this part of the investigation, flow-field properties of hydrogen jets injected into a hypersonic flow are reported. The combustor has a single fuel injection parallel to the main flow from the base. The numerical simulation has been done with finite rate chemistry model using K-ε turbulence model. The results obtained through the numerical simulation of the cavity based fuel injectors are p...

A flamelet-based model for supersonic combustion

The renewed interest in high-speed flight has recently demonstrated the need for the development of hypersonic air-breathing propulsion systems, i.e., in which the ambient air is used as oxidizer. These systems have long been recognized as the most well-suited for hypersonic propulsion. Although a traditional ramjet is most appropriate for supersonic speeds (Mach 3 to 5), hypersonic speeds (Mac...
