Laminar wave dynamics and the associated heat transfer across the spinning film is a highly important process in chemical engineering, but there is still a lack of sufficient investigation of the transfer flux based on the fundamental hydrodynamics parameters. A two‐dimensional computational fluid dynamics simulation of the spinning film on a centrifugal molecular distillator is performed in order to explore the effect of the interfacial wave behavior on the heat transfer. Numerical results reveal that the heat transfer is enhanced by the convective motions in the waves. Resulting from these findings, the relationship between the operation parameters and heat transfer is also discussed.
