Luminescence spectroscopy can be employed to investigate the Brownian motion of upconversion nanocrystals with high spatial resolution and thermal sensitivity. Brownian motion is one of the most ...

Instantaneous distributions of dimensionless temperature T/T0 and fuel mass fraction, with blue dashed lines given by YF=0.05: (top, Case LP-OS1) weak shock with stoichiometric mixture, (middle ...

Streamlines and Streamtubes A streamline is a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a direction). To visualize this in a ...
