“The simulation consists of thermalization, equilibration, and production phases.”
“The magnitude of the observed anisotropic flow effect is sensitive to the degree of thermalization at the collision's earliest moments.”
“The collisional thermalization between electrons and ions is very slow, due to the large difference in their masses, and it occurs on a millisecond timescale.”
thermal
(meteorology) A column of risingair in the lower atmosphere created by uneven heating of Earth's surface.
