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.

Poincaré index formula and analogy with the Kosterlitz-Thouless transition in a non-rotated cold atom Bose-Einstein condensate

open access: yesJournal of High Energy Physics, 2022
A dilute gas of Bose-Einstein condensed atoms in a non-rotated and axially symmetric harmonic trap is modelled by the time dependent Gross-Pitaevskii equation.

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.

Experimental Study on Critical Flow of Supercritical CO2 at Steady State and Model Verification

open access: yesYuanzineng kexue jishu, 2022
When the loss of coolant accident happens in a reactor, because of the high temperature and high pressure in the reactor and the low external pressure, the critical flow may occur at the break due to sharp depressurization and vaporization.

Thermally stratified flow of second grade fluid with non-Fourier heat flux and temperature dependent thermal conductivity

open access: yesResults in Physics, 2018
This attempt explores stagnation point flow of second grade material towards an impermeable stretched cylinder. Non-Fourier heat flux and thermal stratification are considered. Thermal conductivity dependents upon temperature.

Stagnation point flow of viscoelastic nanomaterial over a stretched surface

open access: yesResults in Physics, 2018
Present communication aims to discuss magnetohydrodynamic (MHD) stagnation point flow of Jeffrey nanofluid by a stretching cylinder. Modeling is based upon Brownian motion, thermophoresis, thermal radiation and heat generation.

Numerical simulation of heat transfer features in oblique stagnation-point flow of Jeffrey fluid

open access: yesAIP Advances, 2018
This article concentrates on the characteristics of heat transfer in oblique stagnation point flow of Jeffrey fluid deformed by a linear stretchable surface. The surface temperature is higher than that of the ambient fluid.
