Comparison of cavitation erosion rate with liquid impingement erosion rate
Both cavitation erosion and liquid impingement erosion are phenomena that can cause pipe wall thinning in power plants. The Code for Power Generation Facilities, Rules on Pipe Wall Thinning Management, was published by the JSME (Japan Society of Mechanical Engineers) in 2005. The code says that cavitation erosion shall be prevented either in the design stage or by daily inspection. On the other...
متن کاملMolecular dynamics simulation of Li surface erosion and bubble formation
Structure and dynamical properties of liquid Li containing He atoms were studied by the Molecular Dynamics method at various temperatures and densities and the diffusion coefficients were calculated. A new model of liquid Li surface is developed that shows the stratification of surface layers. The liquid Li sputtering yield, due to bombardment by slow He ions, was calculated for the new model a...
متن کاملWater Impingement Erosion of Deep-Rolled Ti64
In this work, the Liquid Impingement Erosion (LIE) performances of deep-rolling (DR) treated and non-treated Ti64 were investigated. Various erosion stages, from the incubation to the terminal erosion stages, could be observed. A full factorial design of experiments was used to study the effect of DR process parameters (Feed Rate, Spindle Velocity, Number of Passes, Pressure) on the residual st...
متن کاملCFD study of Jet Impingement Test erosion using Ansys Fluent® and OpenFOAM®
The initial aim of this study was to compare OpenFoam and Ansys Fluent in order to verify OpenFoam’s Lagrangian Library and erosion capabilities. However, it was found that previous versions of Fluent have been providing wrong results for the discrete phase and the differences with the latest version (Ansys Fluent 15) are shown. A Submerged Jet Impingement Test is an effective method for studyi...
متن کاملImage Analysis Based Estimates of Regolith Erosion Due to Plume Impingement Effects
Characterizing dust plumes on the moon's surface during a rocket landing is imperative to the success of future operations on the moon or any other celestial body with a dusty or soil surface (including cold surfaces covered by frozen gas ice crystals, such as the moons of the outer planets). The most practical method of characterizing the dust clouds is to analyze video or still camera images ...
