Abstract We presented a comparison of the structural, morphological, and magnetic properties between films cobalt ferrite oxide (CFO), these were deposited with pulsed laser deposition (PLD) spin-coating (SC) technique. In CFO obtained by PLD method, preferential orientation is clearly observed in (004) planes, large grain size distribution associated splashing effect. For SC method have homoge...

Currently gravity irrigation remains the most widely used in agricultural areas and 90 percent of plantings, the water is applied to the plots by gravity. One of the main problems with these systems is erosion, which is a by product of the erosive forces of water over the row, which brings soil loss and therefore decreases in crop yield. Erosion is the removal of surface soil material caused by...

The entry of projectiles into water has been interest to many scientists and engineers, being crucial a wide range engineering applications. problem is nonlinear unsteady phenomenon involving complicated multi-phase flow problems fluid–solid interaction. Many have studying in various conditions through experimental methods numerical methods. In this paper, three-dimensional simulations the are ...

Salt spray splashing on the structural surfaces of ships is a common difficulty in polar navigation. In this paper, experiments are designed to study variation growth peak pure water droplets surface hydrophobic coating with contact angle 90°, and numerical simulation method verified according experiment. The calculated by consistent experiment, calculation error freezing time obtained less tha...

Abstract The controlled splashing of metal droplets plays a decisive role in the kinetics basic oxygen furnace (BOF) process. In this work, mathematical model was developed for predicting size distribution spherical ejected at an impingement zone. Harmonic oscillators are used to describe ejection sites, and upper limit droplet population is calculated through force balance. validated against l...

The impact of droplets at increased environmental pressure is important in many industrial applications. Previous studies mainly considered the process standard or reduced pressure, and effect high unclear. In this study, we experimentally investigate ethanol on dry smooth surfaces pressure. effects splashing rupture crown during are analyzed. results show that surrounding gas with can lead to ...

Plasma-facing components (PFCs) in tokamaks are exposed to high-heat loads during abnormal events such as plasma disruptions and edge-localized modes. The most significant erosion and plasma contamination problem is macroscopic melt splashes and losses from metallic divertor plates and wall materials into core plasma. The classical linear stability analysis is used to assess the initial conditi...
