Latent heat transfer (LHT)

• In addition to the three mode of energy transfer, there is composite phenomenon, which may be recognized as fourth mode of heat transfer, namely latent heat transfer.
• A prime example is the process of distillation, which includes the heat absorbing stage of evaporation, followed by the convective of diffusive movement of the vapor, and ending with the heat releasing stage of condensation. Radiation, convection and distillation are generally of secondary importance
