The calculation of the profile of a liquid film flowing along an inclined cylindrical surface, that is not completely wetted, is presented. Surface tension and contact angle are taken into consideration, and wave motion is neglected. The situation is described by a second order non-linear differential equation. A general solution, represented by a set of elliptical integrals, is given in dimensionless form The case of liquid film hanging from and flowing along a wire of circular cross-section is discussed in detail. For selected values of wire diameter and contact angle a set of profiles was obtained numerically. The liquid hold-up as well as the corresponding interfacial area of gas-liquid contact were obtained. Further, the method enables us to calculate the gas-liquid interfacial area from the liquid hold-up. In the case of a laminar flow, it is possible to carry out a complete analysis of the problem, including no empirical parameter, on solving the Navier-Stokes equation. |
