Abstract

The paper presents the results of research on the vertical falling flow and their analysis. Methods for calculating the gas volume fraction, which are characterized by high accuracy, and are often proposed in the literature. Their accuracy was presented, as well as the methods with the highest computational usefulness when designing devices in which two-phase gas - liquid flow is used.
