Breakdown of Energy Equipartition in a 2D Binary Vibrated Granular Gas
Breakdown of Energy Equipartition in a 2D Binary Vibrated Granular Gas
We report experiments on the equipartition of kinetic energy in a mixture of pairs of different types of grains vibrated in two dimensions. In general, the two types of grains do not attain the same granular temperature, T(g) = 1/2m<v(2)>. However, the temperature ratio is constant in the bulk of …
