Film climbing of particle-laden interfaces
Recent experiments have shown that coalescence of an oil/water/nanoparticle Pickering emulsion contained in a vial induces a nanoparticle-film o climb up the walls of the vial. Here we show that this phenomenon is highly general and can be induced by a variety of particle types, particle izes ranging from a few nm to a few m, and different emulsion types. Many of the features of film growth des...
متن کاملThe Behavior Of Gas Bubbles Entrained In The Liquid Film Of Horizontal Annular Flow
Small entrained vapor bubbles can have a significant impact on the evaporation or condensation of a thin liquid film as may be found in the annular flow of refrigerant in a heat exchanger. For example, past work has indicated that unattached small vapor bubbles serve as sites for vaporization within a film that, on average, would be too thin to support nucleate boiling. Vapor entrained in a thi...
متن کاملExperimental Study on Liquid Film Thickness of Annular Flow in Microchannels
Many studies were carried out to investigate the flow and heat transfer characteristics of two-phase flow in microchannels because of its advantage in improving heat exchange performance, it has been well revealed that liquid film thickness and flow pattern play important roles in determining the heat transfer characteristics. However, these data is still limited to understanding properties of ...
متن کاملDispersion Models for Extremes
We propose extreme value analogues of natural exponential families and exponential dispersionmodels and introduce the hazard slope as an analogue of the variance function. The set of quadraticand power hazard slopes is characterized, and is shown to include well-known distributions such asthe Rayleigh, Gumbel, power, Pareto, logistic, negative exponential, Weibull and Fréchet famili...
متن کاملlaminar flow in annular conduits
the flow of fluids in annular conduits has been studied for over sixty years, however the resulted data are very scattered. in this paper the problem is analytically solved, starting out with navier-stokes equations. a computer solution is used to determine the shape of velocity profiles, the discharge and the friction factor in a large number of concentric and eccentric annular conduits. the e...
