Introduction: Shock processes in heterogeneous materials is a challenging aspect of impact cratering studies. Understanding the equipartition of energy in shocked mixtures of widely varying impedence is necessary to predict a wide range of phenomena, including phase changes, post-shock temperatures, and chemical reactions. Here, we present the results from shock py-rometry experiments on a mixt...

This work studies a series of factors influencing erosion-corrosion in oilfield gathering pipelines steel using the home-made testing pipe flow loop. Results showed that was corroded oil-water flow. The corrosion rate increased with velocity on whole, and addition solid particles would intensify localized corrosion. For test added 2 wt% quartz sand at m/s, portion pure erosion accounted for 47....

Static mixers are in-line devices, which consist of motionless mixing elements, inserted in the given length of the pipe. Homogenization is attained by using the flow energy of the material to be mixed. The mixing effect depends on the continuous separation, distribution, and reunion of particles in the stream of material. There are various element designs available for mixing liquids and they ...

The primary objective is establishing tangible experimental methods and data analyzing methods in order to grasp various phenomena, which were the behavior of ejecta and projectile, the penetration depth and speed of projectile, fractured grains and the pressure distribution, induced by high-speed impact of projectile on sand. The plate impact experiments were conducted using vertical powder gu...

One of soil microbiology's most intriguing puzzles is how so many different bacterial species can coexist in small volumes of soil when competition theory predicts that less competitive species should decline and eventually disappear. We provide evidence supporting the theory that low pore connectivity caused by low water potential (and therefore low water content) increases the diversity of a ...
