Consecutive PIV Analyses on a Finite-Amplitude Pulsating Jet

open access: yesJournal of Fluid Science and Technology, 2009
Pulsating jets are very common and sometimes useful in industrial fields, due to some differences in basic characteristics from steady jets. In this research, the authors focus upon the mechanism of the frequency effect on a finite-amplitude pulsating ...

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 ...
