We have performed molecular dynamics simulations of two component fluid systems to study molecular mechanism of vapor explosion phenomena. In the simulation of vapor film formation, when the hot and cold liquids come into contact, vapor film of the cold liquid immediately appear. The vapor film grows rapidly and retains some thickness, which depends on the temperature difference between the liquids. In the simulation of collapse of vapor film, a droplet of hot liquid was immersed in a bulk cold liquid. Vapor film around the hot droplet shrink gradually in first stage, and then shrink rapidly in second stage.
