Liquid Bridge Ocsillations: Analytical and Numerical Resultsvitational and surface tension forces means that liquid bridges have limited stability on earth. This has lead to interest in the application of processes involving liquid bridge in a micro-gravity environment such as can be achieved in space, see Walter [1].

Viscosity Effects on the Dynamics of Long Axisymmetric Liquid Bridgesoblem has been solved by using an one-dimensional model known in the literature as the Cosserat model, which includes viscosity effects, where the axial velocity is considered constant in each section of the liquid bridge.

Some Problems Raised by Marangoni Instability in Spherical Geometryby two concentric spherical surfaces: the inner one is rigid and uniformly heated while the outer is free: it exchanges heat with the external environment and is submitted to a temperature-dependent surface tension. In a first stage, the spherical support is assumed at rest and the outer surface is 作者: KIN 時(shí)間: 2025-3-22 22:36 作者: Pander 時(shí)間: 2025-3-23 03:26
Stationary Marangoni Instability in a Liquid Layer due to Non-Isothermal Gas Absorptionis studied. As the effects of fluid density are negligibly small at reduced gravity, the mass transfer process can be influenced by a thermal interfacial convection. The analysis shows that the stationary convection sets on not only when the wall temperature is higher than that of the gas (according作者: 他去就結(jié)束 時(shí)間: 2025-3-23 06:21
Three-Dimensional Transient Simulation of Marangoni Flow in a Cylindrical Enclosure under Various Gr isothermal top and bottom walls is studied numerically for various gravity levels.
