Abstract
We study a two-dimensional granular gas of inelastic spheres subject to multiplicative driving proportional to a power |v(x)|δ of the local particle velocity v(x). The steady state properties of the model are examined for different values of δ, and compared with the homogeneous case δ=0. A driving linearly proportional to v(x) seems to reproduce some experimental observations which could not be reproduced by a homogeneous driving. Furthermore, we obtain that the system can be homogenized even for strong dissipation, if a driving inversely proportional to the velocity is used.
