Abstract:
Phenomena related to phase transitions are nontrivial, understanding of
which is of fundamental importance. This thesis deals with dynamics in fluids
at and around phase transitions in equilibrium as well as nonequilibrium
situations. In equilibrium case we study various transport properties in the
vicinity of phase coexistence with particular emphasis on the enhancement
of these quantities as one approaches the critical point, i.e., dynamic critical
phenomena. In out-of-equilibrium case, our focus is on the coarsening
dynamics following rapid quench of a homogeneous system into the phase
coexistence region.
