OSTI ID:6920822
Experiments were performed to determine the statistical characteristics of interfacial waves in free-falling films and to gain a better understanding of turbulent activity in thick wavy films. The development of a new conductance probe made it possible to accurately measure instantaneous film thicknesses greater than two millimeters. This study focuses on interfacial waves in turbulent falling liquid films with average film thicknesses in the range 0.5 to 1.75 mm. Characterization of the wave profiles, wave frequency spectra and average film thickness are presented for a wide range of flow rates.
