A review of theoretical and experimental aspects of homogeneous and heterogeneous bubble nucleation (valuable in LNG studies) covers recent developments in nucleation theory, which include hydrodynamic and diffusion constraints, gas-phase nonidealities, and heterogeneous nucleation. Large superheating may be involved in the dangerous and destructive contact vapor explosions observed in metallurgical and paper smelt processing and pose a potential hazard in the operation of nuclear reactors, in cryogenic systems, and in the transport of liquefied natural gas. A large number of the measured limits of superheat of pure components are close to 88-90% of the critical temperature. Where calculations can be made, these measurements are in agreement with predictions from classical nucleation theory. The criteria deduced from theory for homogeneous and heterogeneous nucleation lead to one plausible mechanism for the initiation of the dangerous and destructive contact vapor explosions.
