Stagnation temperature and pressure distortion effects upon the response of an aerofoil

International Journal of Heat and Fluid Flow, 1980
Abstract A series of experiments is described in which an uncambered aerofoil, set at a constant incidence was traversed incrementally through a range of combined stagnation temperature/stagnation pressure distortions. Measurement of the static pressure distribution around the aerofoil yielded lift coefficient variations.

Design Space Exploration of Stagnation Temperature Probes via Dimension Reduction

Volume 2C: Turbomachinery, 2020
Abstract The measurement of stagnation temperature is important for turbomachinery applications as it is used in the calculation of component efficiency and engine specific fuel consumption. This paper examines the use of polynomial variable projection to identify dimension reducing subspaces for stagnation temperature probes.

Measurements of Stagnation-Point Temperature with High-g Telemetry

IEEE Transactions on Aerospace and Electronic Systems, 1968
Measurement of phenomena associated with free-flight models in ballistic ranges has been made possible with the development of a stable on-board miniaturized telemetry system that will withstand large gun-launch accelerations. The results of body temperature measurements behind the stagnation point with thin-film temperature gauges are presented and ...

Optical Determination of Stagnation Temperature Behind a Gas Sampling Orifice

Journal of Heat Transfer, 1990
A technique has been developed for measuring the temperature during a transient combustion event. It combines the features of atomic resonance absorption and direct sampling to produce a relatively simple, intrusive diagnostic technique to obtain time-resolved measurements.

Stagnation and nocturnal temperature jumps in a desert region of low relief

Boundary-Layer Meteorology, 1981
Observations of mesoscale variations in temperature and wind fields in a desert environment are presented and discussed. In particular the influence of low relief under conditions of strong stability is highlighted and stagnant flow is shown to occur below a critical Froude number of 1.5.

Stagnation-Point Heat Transfer in a High-Temperature Inert Gas

The Physics of Fluids, 1962
Stagnation-point similarity solutions of the laminar boundary-layer equations are calculated for a thermally and calorically perfect gas with Prandtl number ⅔ and viscosity proportional to a power of the absolute temperature (μ ∝ T1−α). The parameter α is varied from 0 to 0.5, and the enthalpy ratio across the boundary layer from 0.01 to 0.80.
