  We review and discuss recent advances in the simulation of bulk critical
phenomena in model fluids. In particular we emphasise the extensions to
finite-size scaling theory needed to cope with the lack of symmetry between
coexisting fluid phases. The consequences of this asymmetry for simulation
measurements of quantities such as the particle density and the heat capacity
are pointed out and the relationship to experiment is discussed. A general
simulation strategy based on the finite-size scaling theory is described and
its utility illustrated via Monte-Carlo studies of the Lennard-Jones fluid and
a two-dimensional spin fluid model. Recent applications to critical polymer
blends and solutions are also briefly reviewed. Finally we consider the outlook
for future simulation work in the field.
