Water Impingement Erosion of Deep-Rolled Ti64

Water 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...

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...

Application of Lattice Boltzmann and Cellular Automata in Erosion Modeling for Deep-Water Turbidity Current

The objective of hybrid modeling is to obtain a balance of geological reality, the representation of spatial uncertainty with a fixed set of initial parameters and the capability of being conditioned to the hard data as well. Reasonable algorithms have been constructed in previous works (Pyrcz et al. 2003, 2005, Michael et al. 2008 and Leiva et al. 2009). However, realism of erosion and deposit...

Effect of soil composition on critical water erosion shear stress

Evaluation of Factors Affecting Water Erosion along Skid Trails

Water erosion causes severe soil damage in northern forests of Iran which is associated with different rut depths in skid trails. The aim of this study was to assess rutting and soil displacement on skid trails to mitigate water erosion. Therefore the research was carried out in eight parcels of district No 3 of Shafarood Forest in the North of Iran. In order to evaluate the amount of erosion i...
