Abstract The von Karman analogy between heat transfer and momentum transfer in turbulent fluids is shown to apply to heat transfer through wavy liquid films in horizontal, stratified, gas‐liquid flow. Nusselt numbers predicted from the analogy are shown to be in good agreement with experimental data for air‐water flows involving three‐dimensional wavy films and large‐amplitude roll waves. The Nusselt numbers encountered with these turbulent water films are found to be in the same range as those associated with condensation of organics in horizontal tubes under stratified flow conditions.
