Showing papers on "Shell balance published in 2004"
TL;DR: In this paper, the authors considered a flow of hot fluid having a harmonic component superposed on the mean flow velocity is considered flowing through an insulated cylindrical shell, and the results of the theoretical studies were presented related to instability regions due to a pulsatile flow of a hot fluid through a cylinder shell and the effect of fluid temperature and excitation parameter on the behavior of dynamic instability of the system is examined.

TL;DR: In this article, the interaction of a spherical shock wave with an elastic circular cylindrical shell immersed in an infinite acoustic medium is studied, where the wave source is quite close to the shell, causing deformation of a small portion of the shell.
Abstract: The paper studies the interaction of a spherical shock wave with an elastic circular cylindrical shell immersed in an infinite acoustic medium. The shell is assumed infinitely long. The wave source is quite close to the shell, causing deformation of just a small portion of the shell, which makes it possible to represent the solution by a double Fourier series. The method allows the exact determination of the hydrodynamic forces acting on the shell and analysis of its stress state. Some characteristic features of the stress state are described for different distances to the wave source. Formulas are proposed for establishing the safety conditions of the shell.

TL;DR: In this paper, the authors used momentum balance models to predict hold up and pressure drop for both annular and stratified regimes, and found that the momentum balance calculation tended to under predict both the hold-up and pressure-drop.
