Falling films of pseudoplastic liquids

The Chemical Engineering Journal, 1974
Abstract An experimental and analytical study has been conducted on thin film flow of pseudoplastic, non-Newtonian liquids down a smooth vertical plate. Mean film thickness, friction coefficient, wavelength and entrance length preceding the first noticeable waves have been examined experimentally.

Performances of falling film evaporators

Journal of Dairy Research, 1991
SummaryThe performances of falling film evaporators used in the New Zealand dairy industry for concentrating skim milk, whole milk and buttermilk were evaluated by determining (1) the kg steam used per kg water evaporated, and (2) the heat transfer coefficient of each pass in the evaporators. A computer program was used to calculate the results.

Turbulence in falling liquid films

AIChE Journal, 1955
AbstractOn the basis of fluid dynamic and heat transfer studies on falling‐film towers by various investigators, it has been commonly accepted by most workers that the liquid flow is essentially streamline in nature for liquid‐film Reynolds numbers under 1,800 to 2,000; conseuquently it would be expected that the rate of physical gas absorption in such

Shear-imposed falling film

Journal of Fluid Mechanics, 2014
AbstractThe study of a film falling down an inclined plane is revisited in the presence of imposed shear stress. Earlier studies regarding this topic (Smith, J. Fluid Mech., vol. 217, 1990, pp. 469–485; Wei, Phys. Fluids, vol. 17, 2005a, 012103), developed on the basis of a low Reynolds number, are extended up to moderate values of the Reynolds number.

Falling film on a sphere

The Chemical Engineering Journal, 1974
Abstract The Navier-Stokes equation has been solved for the case of creeping flow of a film on a sphere. The results have shown that the parabolic velocity profile is in remarkably good agreement with the present analysis.

A Compact Falling Film Absorber

Advanced Energy Systems, 2004
The paper presents a new design of a falling film absorber that could considerably reduce the absorber size without penalizing on the vapor and coolant side pressure drops. The proposed design is based on the fundamental characteristics of an efficient absorber design: large liquid-vapor interfacial area and good wetting characteristics.

Low Kapitza falling liquid films

Chemical Engineering Science, 2017
Abstract Low Kapitza liquids, such as mineral or vegetable oils, have a low surface tension and a high viscosity. In these liquids, capillary forces and extensional viscous dissipation play an equal role in damping interface deformation, resulting in a configuration which challenges the long wavelength assumption at the origin of low-dimensional ...

Coarsening dynamics of falling-film solitary waves

Physical Review E, 1996
Because interfacial wave dynamics on a falling film involves quasisteady localized solitary pulses, its complex spatiotemporal dynamics exhibits certain generic features and scalings. We construct a statistical theory for such dynamics from our earlier theory for binary pulse interaction [Physica D {bold 63}, 299 (1993); Phys. Rev. Lett.

The falling film MSF evaporator

Desalination, 1976
Abstract The application of falling film heat transfer to the MSF cycle permits use of CO2 for scale prevention at no cost and the building of efficient very small capacity units with heating surfaces that are fully accessible during operation. It also becomes possible to use doubly fluted tubes for a 2 3 saving in heating surface requirements.

Spatiotemporal instability of an electrified falling film

Physical Review E, 2016
The linear spatiotemporal response to an infinitesimal disturbance is analyzed for an electrified falling film based on the Orr-Sommerfeld boundary value problem. Four spatial branches are identified, which lose their spatial symmetry in the presence of an electric field.
