Development and application of stagnation pressure probe for dusty gas measurements

Review of Scientific Instruments, 1995
The design, development and application of a fast response probe for measuring gas phase pressures under dusty flow conditions are described. Measured results for this probe, historically designated as the ‘‘Snob’’ probe, demonstrate satisfactory resolution of past limitations on output performance.

Shock Oscillations in a Supersonic Diffuser Flow with Varying Stagnation Pressure

2019
The flow in supersonic wind tunnel diffusers is usually transonic in nature, and the formation of a normal shock just downstream of the diffuser throat region is required for power economy. The behavior of this starting normal shock decides the start or unstarts of a supersonic wind tunnel.

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 ...

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 Mechanics
To 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

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.
