Stagnation Pressure Transient Control in a Supersonic Blowdown Wind Tunnel Test Facility

Materials Today: Proceedings, 2016
Abstract Research in the area of wind tunnel flow parameters control has been intensified in recent years, in an attempt to improve quality and efficiency of the wind tunnel operation. In this paper, stagnation pressure transient control in a supersonic blowdown-type wind tunnel is considered, with the aim of increasing available measurement time and

Randomised, controlled pilot to compare collagen and foam in stagnating pressure ulcers

Journal of Wound Care, 2012
Objective: To compare the clinical efficacy of a collagen dressing covered with a foam dressing with the same foam used as a primary dressing in stagnating granulating pressure ulcer patients. Method: Patients were randomised to receive either a foam dressing (Suprasorb P; Lohmann & Rauscher) as a primary dressing (group A), or a combination of a ...

Inlet Stagnation Pressure Loss Estimate for a Simplified Thrust Model

47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009
In a previous work, the author presented a simplified thrust model to be used in predicting the performance of high-speed aircraft. That model contained an ad hoc estimate of the stagnation pressure loss in the inlet/diffuser of the engine. The current analysis attempts to capture some of the actual physics of the flow, modeling the incoming flow as a ...

Stagnation pressure effect on the supersonic minimum length nozzle design

The Aeronautical Journal, 2019
ABSTRACTThe 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 uniform and parallel flow at the exit section.

Pneumatic Component Characterization: Use of Measured Stagnation Pressures

2010
This paper presents the advantages of using upstream and downstream stagnation pressures instead of static pressures to determine the flow characteristics of a pneumatic component. A proposal to measure directly stagnation pressures (sum of static and dynamic effects) is compared to the use of calculation to obtain the stagnation pressure from static ...
