  Kinetic simulations based on the Eulerian Hybrid Vlasov-Maxwell (HVM)
formalism permit the examination of plasma turbulence with useful resolution of
the proton velocity distribution function (VDF). The HVM model is employed here
to study the balance of energy, focusing on channels of conversion that lead to
proton kinetic effects, including growth of internal energy and temperature
anisotropies. We show that this Eulerian simulation approach, which is almost
noise-free, is able to provide an accurate energy balance for protons. The
results demonstrate explicitly that the recovered temperature growth is
directly related to the role of the pressure-strain interaction. Furthermore,
analysis of local spatial correlations indicates that the pressure-strain
interaction is qualitatively associated with strong-current, high-vorticity
structures, although other local terms -- such as the heat flux -- weaken the
correlation. These numerical capabilities based on the Eulerian approach will
enable deeper study of transfer and conversion channels in weakly collisional
Vlasov plasmas.
