• Pore-scale CO 2 foam bubble flow, texture and trapping dynamics at high pressure. A comprehensive laboratory investigation of essential features phenomena during dynamic flow supported by the population balance model framework. The for mobility control in porous media is dictated texture, or density, which commonly expressed as number bubbles per unit flowing gas. In most high-pressure studie...

foam injection is becoming a standard conditioning agent when tunnelling with an earth-pressure balanced shield, resulting in an increasing interest in this technique. the technique is mostly based on empirical rules and experience. to be able to determine what foam and how may foam has to be injected for different soils, it is necessary to know the mechanical parameters of the foam-water-soil ...

High-density polyethylene is a high-strength, and low-weight material system. Besides numerous applications in variety of fields products, its machining for generation holes rather difficult with traditional methods such as drilling the process not very conducive composites due to associated damage. Hence, non-contact removal laser provides an appealing, cost-effective, accurate, fast alternati...

We present measurements of the spectral distribution of transition radiation generated by electrons of momentum 1 to 10 GeV/c in different radiator types. We investigate periodic foil radiators and irregular foam and fiber materials. The transition radiation photons are detected by prototypes of the drift chambers to be used in the Transition Radiation Detector (TRD) of the ALICE experiment at ...
