Impact of Stagnation Temperature and Nozzle Configuration on Rarefied Jet Plume Interactions [PDF]

open access: yesJournal of Spacecraft and Rockets, 2022
The canting axis of thrusters on space platforms, which likely operate in a vacuum environment with a high degree of flow rarefaction, is significant in order to create the desired torque for manoeuvring, maintaining orbit, eliminating perturbation forces, docking, etc.

Stagnation temperature measurement using thin-film platinum resistance sensors [PDF]

open access: yesMeasurement Science and Technology, 2013
The measurement of stagnation temperature in high-speed flows is an important aspect of gas turbine engine testing. The ongoing requirement to improve the accuracy of such measurements has led to the development of probe systems that use a thin-film platinum resistance thermometer (PRT) as the sensing element. For certain aspects of engine testing this

On the hydrodynamics and heat convection of an impinging external flow upon a cylinder with transpiration and embedded in a porous medium [PDF]

open access: yes, 2017
This paper extends the existing studies of heat convection by an external flow impinging upon a flat porous insert to that on a circular cylinder inside a porous medium.

Deposition of graphenic nanomaterials from elevated temperature premixed stagnation flames

open access: yesApplications in Energy and Combustion Science, 2023
The work examines the unique nanostructure of carbon nanoparticles deposited from sooting premixed flames with flame temperatures exceeding 2200 K. This flame temperature regime has previously been shown to transition from typical soot formation conditions to a regime whereby the flame-form carbon adopts a nanostructure considerably more ordered than ...

Stratification in steelmaking ladles [PDF]

open access: yes, 1993
The problem of temperature stratification in a steelmaking ladle is considered. There are three distinct zones in the flow, the wall boundary layer, the bottom stagnation zone and the central plug flow.

Improved real-space genetic algorithm for crystal structure and polymorph prediction [PDF]

open access: yes, 2008
Existing genetic algorithms for crystal structure and polymorph prediction can suffer from stagnation during evolution, with a consequent loss of efficiency and accuracy.

Computer program determines gas flow rates in piping systems [PDF]

open access: yes, 1966
Computer program calculates the steady state flow characteristics of an ideal compressible gas in a complex piping system. The program calculates the stagnation and total temperature, static and total pressure, loss factor, and forces on each element in ...

Smooth leading edge transition in hypersonic flow [PDF]

open access: yes, 1999
The boundary layer transition along the attachment line of a smooth swept circular cylinder in hypersonic flow is investigated in a blowdown wind tunnel. A wide range of spanwise Mach numbers Me (3.28 to 6.78) is covered with the help of different models

Flat Plate Aluminum Heat Pipe Collector with Inherently Limited Stagnation Temperature

open access: yesEnergy Procedia, 2014
This paper presents a new flat plate collector technology based on heat pipes. The use of heat pipes can lead to several advantages over direct flow collectors: A simple hydraulic interconnection, an inherently limited stagnation temperature and substitution of copper.
