Langevin dynamics computer simulations have been performed for a two-demensional Lennard-Jones fluid quenched into the coexistence region of its liquid-vapor phase diagram. For late stages of the phase separation process, the average radius of the liquid clusters is found to grow proportional to time raised to the exponent of 1 over 4. This growth law is analyzed theoretically and compared to recent molecular dynamics and Monte Carlo results. Details of the different simulation methods are critically discussed.
