  The time evolution of temperatures of anisotropic nanoparticles in two and
three-body systems are simulated for various relative orientations.
Nanoparticles are immersed in a thermal bath at constant temperature. It is
shown that in two-body systems, the relative orientation of nanoparticles could
drastically affect the dynamics of temperature evolution and thermalization
time scale. Moreover, in some configurations, the temperature difference in
initial state has a minor effect on the dynamics of temperatures. In three-body
systems, the orientation of the third nanoparticle influences the temperature
dynamics, which allows one to control the thermalization time scales between
anisotropic nanoparticles. Also, in addition to previously known contribution
of the smallest distance between isotropic nanoparticles on the thermalization
time scales, it is shown that the nanoparticles' orientations are more
important in some particular arrangements.
