Axisymmetric laminar flow of two-phase medium inside the system of two coaxial pipes
Journal Title: Energetika - Year 2018, Vol 0, Issue 0
Abstract
The problem of the axisymmetric laminar flow of a two-phase (liquid-gas) flow inside the infinite system of coaxial tubes with a circular cross-section located vertically is considered. Analysis of the analytical solution showed that increase in velocity of the gas flow leads to the appearance of the hold-up regime (then the velocity of media at the interface is zero) and flooding regime (when volume flow of liquid is zero). It is discovered that these regimes occur at lower values of the velocity of the gas flow for the heated medium in comparison with the cold medium.

EU-CIRCLE methodological approach for assessing the resilience of the interconnected critical infrastructures of the virtual city scenario to climate change
This paper introduces a methodological approach for identifying the resilience of interconnected EU critical infrastructures to climate change. The proposed approach tries to establish a consequence-based modelling frame...
The method of rational dispatching a sequence of heterogeneous repair works
For critically important power systems, some repair works should be performed by one repair brigade at the same time. Conditions for performing different works are often characterized by uncertainties. In practice, the t...
