Rotating detonation waves in annular gap with variable stagnation pressure
Shock Waves, 2021We consider a three-dimensional unsteady flow with one, two, or four rotating detonation waves arising in an annular gap of an axially symmetric device between two parallel planes perpendicular to its symmetry axis. The corresponding problem is formulated and studied.

Stagnation pressure effect on Prandtl Meyer function for air
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2017When the stagnation pressure of a perfect gas increases, the specific heat and their ratio do not remain constant anymore and start to vary with this pressure. The gas does not stay perfect. Its state equation change and it becomes for a real gas. In this case, the effects of molecular size and intermolecular attraction forces intervene to correct the

Recursive identification of stagnation pressure in wind tunnel system
2016 35th Chinese Control Conference (CCC), 2016Identifying an accurate model of the stagnation pressure on-line will benefit the design of the controller and improve the quality of the wind tunnel experiments. This paper focuses on the recursive identification of the stagnation pressure in the wind tunnel system.

Stagnation pressure effect on the supersonic minimum length nozzle design
The Aeronautical Journal, 2019The aim of this work is to develop a calculation model based on the method of characteristics making it possible to study the effect of the stagnation pressure of the combustion chamber on the 2D and axisymmetric minimum length nozzle design giving a ...

A Stagnation Pressure Probe for Supersonic and Subsonic Flows
Aeronautical Quarterly, 1974The usefulness of a probe which can sense the absolute value of the stagnation pressure in supersonic flow has long been recognised. In the past such a probe has not been available and therefore it has been necessary to infer this fundamentally important

Isentropic air flows at high stagnation pressures
Fluid Dynamics, 1976 Calculations of the gasdynamic parameters of air using different equations of state for a real gas in one-dimensional formulation were carried out in [1-3]. The results from these papers are of a limited nature, as the equation of state of a real gas, which occurs in the system of starting equations, is valid for a quite narrow range of total pressures

Prediction of inviscid stagnation pressure losses in supersonic inlet flows
AIAA Journal, 1990An effort is made to quantify the stagnation pressure losses associated with shock-wave systems that may be present in such high Mach number flows as those of scramjet hypersonic diffusers.
