A novel particle method of characteristics (PMOC) to simulate unsteady pipe flows is introduced and validated in the present study. Contrary to the conventional method of characteristics (MOC), the present formulation is built by reallocating the com

An efficient Godunov-type numerical method with second-order accuracy was developed to simulate the water-hammer problem in piping. The exact solutions of the Riemann problem were analysed and illustrated on the intriguing solution diagram by properl

Flow-assisted corrosion (FAC), an aspect of erosion/corrosion (E/C), is a mechanism of piping degradation that causes a loss of material from the inside of the piping and then thinning of the wall....

Wave propagation of low-void-fraction, two-phase bubbly flow is analyzed from the compressibility of a bubble and an assumption of homogeneity for steam bubbles. The phase velocity and attenuation calculated from the model are strongly dependent on f

In this paper, wave propagation in a homogeneous, low void fraction, two-phase air-water bubbly flow is analyzed through the compressibility of a single bubble to derive a P({rho}) relation; the dispersion relation is then derived by a homogeneous mo

A simple model is developed for predicting the dispersion and attenuation of sound in a homogeneous low void fraction air—water two-phase bubbly flow. The relationship between interfacial area density and sound attenuation is derived for dimensionl

A model is developed for predicting the sound velocity in low void fraction, homogenous steam/water two-phase bubbly flow. It is based on an analysis of the compressibility of a typical bubble. The sound velocity predicted is found to be strongly dep
