Control and evaluation of particle impact conditions in a sand erosion test facility

Practical estimation of erosion damage caused by solid particle impact

“…A sand blast type erosion test rig was used in this study [9]. This rig was composed of a reservoir tank, valve, acceleration tube and a specimen holder.…”

“…100 m s −1 by SiO 2 -2 (a) and SiC particles (b). The impact velocity varied with the particle size at the same tank pressure, as mentioned above and in a previous report [9], and was then modified according to the impact velocity dependence of erosion such as shown in Fig. 6.…”

Normal impact of sand particles with solar panel glass surfaces

“…The distance to glass target is chosen to be 30 cm. The compressor supplies a pressure of 5 psi which results in a sand particle speed of approximately 10-12 m/s [33] for a duration of 60 s. This is considered a high wind velocity for a typical desert region. After sand blasting, the samples are rinsed with copious isopropanol followed by drying in a convection oven at 70°C for 20 mins.…”

Effect of air-borne particle–particle interaction on materials erosion

“…In particular, in this study, the effect of particle-particle interaction on both erosion rate and erosion pattern was compared with that without including the particle-particle interaction and also experimental results. Both airflow behavior and particle behavior at the interaction region were studied in depth Regarding the effects of particle-particle interaction on material erosion, several interesting works have been performed using analytical analysis [4][5][6], numerical modeling [7][8][9][10] as well as experimental measurements [11,12]. For analytical analysis, Andrews and Horsfield [4] developed a theoretical model for particle-particle interaction to study the effects of particle flux on the erosion process.…”
