The Cosmic Nozzle [PDF]

open access: yesSymposium - International Astronomical Union, 1996
The cosmic nozzle is a channel with flowing hot gas in a system containing the following components: stars, a hydrostatic gaseous corona and a cavity with hot gas in the central part of the system. In the quasi one-dimension approximation, the following solution of the cosmic nozzle problem about cosmic nozzle was obtained Here (ν,ω, T, σ) are the ...

Characterization of Particle Number Setups for Measuring Brake Particle Emissions and Comparison with Exhaust Setups

open access: yesAtmosphere, 2023
The stringency of vehicle exhaust emissions regulations resulted in a significant decrease in exhaust particulate matter (PM) emissions over the years. Non-exhaust particles (i.e., from brakes and tyres) account for almost half or more of road transport ...

Generation of nanoparticles in the concentrated energy (laser beam) and gas flow

open access: yesAviation, 2004
The method of generation and selection of small nanoparticles in the airflow is considered in this paper. To melt the material (stainless steel), a concentrated energy flow – a pulsed solid‐state laser beam – was used.
