A press with oppositely acting rams which has the features of maintaining parallel press plattens during operation and also good alignment of the plattens in relation to the central pressure axis. Two closed links are positioned side by side and each link carries a platten support cantilevered ...
Integral Methods for Two-Phase Flow in Hydraulic Systems Wolfgang Wulff, in Advances in Heat Transfer, 1998 I Importance of Two-Phase Flow A phase is a system, or a portion of a system, composed of any number of chemical constituents that is homogeneous and has a definite boundary [43]. ...

Successful production has been achieved from shale gas and shale oil reservoirs by technologies such as directional drilling and multi-stage hydraulic fracturing (Coulter, 1976; Hartsock and Warren, 1961; Meese et al., 1994; Pokalai et al., 2015; De Silva et al., 2015; Wanniarachchi et ...

The connection members can be projected in a first stage to effect alignment and in a subsequent stage to effect hydraulic and/or electrical connection. The mounting of the units and receptacle is such as to permit retrieval of the module in the event of a failure to withdraw the connection ...
Lacq gas field in France4, the Groningen field in the Netherlands5); seismicity correlated to the injection of wastewater and enhanced oil recovery6, to shale gas hydraulic fracturing7,8,9, and to hydraulic stimulation for enhanced geothermal systems, which operates in a similar way to ...
Reliable and comprehensive predictive tools for the frictional pressure drop (FPD) are of particular importance for systems involving two-phase flow condensation. However, the available models are only applicable to specific operating conditions and chan
the key technology of enhanced geothermal system is the process of continuous heating and recovery of cold fluid injected into the ground through the effective flow channel formed by large-scale fractures produced by hydraulic fracturing. This requires accurate characterization and calculation of the mass...
This is due to the hydraulic jump becoming stronger as a result of the increase of the momentum. Therefore, the liquid reaches the upper side of the pipe wall, hence, the bubble tail disappears as the change of the plug flow becomes the slug flow. Next, the edge of the elongated bubble...
