Integral equations for viscous hypersonic nozzle flow

Investigation of Hypersonic Nozzle Flow Uniformity Using NO Fluorescence

Planar laser-induced fluorescence visualisation isused to investigate nonuniformities in the flow of a hyper-sonic conical nozzle. Possible causes for the nonuniformityare outlined and investigated, and the problem is shown to bedue to a small step at the nozzle throat. Entrainment of coldboundary layer gas is postulated as the cause of the signalnonuniformity.

A multidimensional gas-kinetic BGK scheme for hypersonic viscous flow

This paper concerns the development and application of a gas-kinetic scheme based on the Bhatnagar–Gross–Krook (BGK) model for the Navier–Stokes equations in the study of hypersonic viscous flow. Firstly, we extend the gas-kinetic Navier–Stokes solver [K. Xu, A gas-kinetic BGK scheme for the Navier–Stokes equations and its connection with artificial dissipation and Godunov method, J. Comput. Ph...

Hypersonic-Flow Governing Equations with Electromagnetic Fields

The paper deals with the formulation of a consistent set of governing equations apt to describe the physical phenomenology comprising the hypersonic flow field of an ionized gas mixture and the electromagnetic field. The governing equations of the flow field and those of the electromagnetic field are revisited in sequence and differences or similarities with past treatments are pointed out and ...

Perspectives on Hypersonic Viscous and Nonequilibrium Flow Research

Approximate Viscous Shock-Layer Analysis of Axisymmetric Bodies in Perfect Gas Hypersonic Flow

In this paper, an approximate axisymmetric method is developed which can reliably calculate fully viscous hypersonic flow over blunt-nosed bodies. In this method, a Maslen’s second-order pressure expression is used instead of the normal momentum equation. The combination of Maslen’s second-order pressure expression and viscous shock layer equations is developed to accurately and efficiently com...
