The rate of condensation of water vapor determines the operation
of a number of engineering processes. For example, condensation
plays a key role in applications such as air conditioning,
electricity generation, refrigeration, reactor safety, aerospace,
desalination, and some heat exchangers. Environmental and economic
pressures are imposing a need to design increasingly efficient
systems. As a result, we need to enhance our understanding
on the physics of condensation in the presence of non-condensable
gases.
