TL;DR: In this paper, Density wave oscillations (DWO) and Ledinegg instabilities are analyzed for boiling and condensing systems in a single tube, based on a numerical model solved with a least squares spectral element method which is characterized by negligible numerical diffusion and high accuracy.
Abstract: In this work Density Wave Oscillations (DWO) and Ledinegg instabilities are analyzed for boiling and condensing systems in a single tube. The analysis is based on a numerical model solved with a least squares spectral element method which is characterized by negligible numerical diffusion and high accuracy. Stability limits are constructed and compared with available correlations. The analysis is extended to sub-cooled, saturated and over-heated inlet conditions. Finally a discussion regarding the occurrence of these phenomena in condensing systems is presented.
