Suction of splash after impact on dry quick sand
It is well known that a splash occurs when an object impacts at high velocity on a liquid’s surface. If the impact is fast enough, surface tension and air pressure gradients pull the crown-shape splash all the way towards the axis of symmetry, making it to collapse and seal the surface. In this paper we show that splash and surface sealing are also observed in impacts on soft, dry sand. We obse...
متن کاملSplash and anti-splash: observation and design.
We experiment with releasing ethanol droplets, from a specific height, onto both flexible and rigid surfaces. The study of the resulting impact and splashing provides new insights into the mechanisms of the short time-scale dynamics. Tuning and even suppressing a splash can be achieved by the use of elastic membranes with controlled tension. Under certain experimental conditions, i.e., droplet ...
متن کاملFecal coliform dispersal by rain splash on slopes
The movement of fecal pathogens from land to surface and ground water are of great interest because of the public health implications. Non-structural best management practices that control the timing, volume, and placement of animal manures are commonly used to limit opportunities for fecal pathogens to enter water bodies. Increased infiltration capacity, water and waste diversions, and vegetat...
متن کاملMeasurement and Comparison of Soil Splash Rates under the Influence of Acidity and Rain Intensity
Nowadays, acid rain serves as one of the most serious environmental problems has affected many regions in the world. This phenomenon is characterized by many environmental impacts, such as soil contamination and degradation. Acid rain immediately affects soil, causing soil particles to breakdown and be dispersed; this is the first step to initiate the soil erosion. Therefore, in this study, the...
متن کاملEffects of Crop Canopies on Rain Splash Detachment
Crops are one of the main factors affecting soil erosion in sloping fields. To determine the characteristics of splash erosion under crop canopies, corn, soybean, millet, and winter wheat were collected, and the relationship among splash erosion, rainfall intensity, and throughfall intensity under different crop canopies was analyzed through artificial rainfall experiments. The results showed t...
