The main goal of the book is generalization of the existing knowledges of the wavy flow of falling thin liquid films and transfer processes in wave regimes. The methods of local measurements of hydrodynamic parameters have been analyzed. The theoretical models of wave motion taking into account non-linearity, non-stationarity, dispersion, multi-wave character and other effects have been stated. The waves of different types, including solitons, have been described theoretically and experimentally. The influence of waves on the transfer processes through the interface has been demonstrated. The mechanisms of heat and mass transfer enhancement in wave films have been analyzed. |
