ABSTRACT

In this work, two-phase flow boiling instabilities in vertical and horizontal system are presented. The stead-state system pressure-drop characteristics are determined by a numerical solution of the governing equations as derived from the Drift-Flux model. The transient characteristics of the two-phase flow are obtained for various parameters and the results are presented in graphical and tabular forms. The numerical solutions are determined using an explicit finite difference scheme. A satisfactory agreement between the theory and experiments is obtained.
