Stagnation Pressure Transient Control in a Supersonic Blowdown Wind Tunnel Test Facility
Materials Today: Proceedings, 2016Abstract 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, 2012Objective: 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, 2009In 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, 2019ABSTRACTThe 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
2010This 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 ...

Volumetric Reconstruction Of Stagnated Wake Structures In Adverse Pressure Gradient
Proceedings of the International Symposium on the Application of Laser and Imaging Techniques to Fluid MechanicsTo gather insights about turbulent structures of a wake in adverse pressure gradient, a wind tunnel model is investigated with PIV methods. A flat plate of L = 1.058 m at zero angle of attack is placed in the MUB wind tunnel at TU Braunschweig. The wake convects downstream into a carefully designed diffuser, where it undergoes a pressure increase of ∆c
