The convective heat transfer of the plume of a 120-N thruster is investigated experimentally and numerically. Numerical results agree well with experimental results in that there is a nonlinear decrease in convective ...
Pressure-sensitive paint(PSP) technique was employed to experimentally investigate the aerodynamic force effect of vacuum plume in this study. The characterization and comparison for two types of PSP were firstly cond...
The redistribution of the electrically charged cold plasma of ionospheric origin involves the equatorial,low,mid,auroral,and polar-latitude regions in a multi-step,system-wide process linking the regions of geospace.O...
The back-sputtering effect of an electric thruster used in a vacuum chamber has an adverse effect on the thruster, vacuum chamber and experimental equipment. An anti-sputtering target (AST) can extend the operating ...

This paper introduces a newly developed vacuum Plume effects Experimental System(PES) used for plume effect tests of rocket engines and vacuum heat tests of satellites. The design level, manufacturing technique, and t...
When the liquid propellant thruster works,its plume field would contain many propellant liquid droplets,especially at pulse state.Liquid droplets may move along with the gas flow and deposit on the components of space...

A calculation model for mechanical exhaust rate in large-space building in the case of cabin fire is proposed through theoretical analysis. Full-scale hot smoke tests are then performed to study the cabin fire spreadi...
