Hydraulic fracturing technology is the most important stimulate method to develop unconventional oil and gas resources. The incomplete flowback of the fracturing fluid causes great seepage resistance for hydrocarbon production. Adding cleanup additive composed of surfactant is an effective method to increase the flowback rate, which is more closely related to the oil/water interfacial tension

ANSYS CFX, which is commercial computational fluid dynamics (CFD) code applying the method of finite volumes to solve Navier-Stokes equations describing laminar and turbulent behavior of fluids with Reynolds-averaged Navier-Stokes equations (RANS) method.
Gerotor Hydraulic Pumps from the Hytec Group of Companies, Africa’s largest supplier of hydraulics, pneumatics and automation products. For cooling, filtration or lubriion circuits at low pressures in industrial or mobile appliions, e.g. plastics processing
Spring force opposes the hydraulic force, so that only enough oil flows past the valve to supply the secondary circuit at the desired pressure. The spring setting is adjustable. When outlet pressure reaches that of the valve setting, the valve closes except for a small quantity of oil that bleeds from the low-pressure side of the valve, usually through an orifice in the spool, through the

Another negative feature that make the use of hydraulic drives more challenging is the starting behavior of hydraulic motors, especially those based on a swashplate design: the motor is initially subject to loads and static friction before it suddenly starts to move.
hydraulic behavior of the system (in terms of performance, stability, etc.), but also to observe the thermal characteristics of the hydraulic circuit and assess the need for heat exchangers.
Due to the negative effects on maintenance intervals, swelling behavior and lifetime of the seals in case of the use of hydraulic oils that have not been approved as …
A simple hydraulic system consists of hydraulic fluid, pistons or rams, cylinders, accumulator or oil reservoir, a complete working mechanism, and safety devices. These systems are capable of remotely controlling a wide variety of equipment by transmitting force, carried by the hydraulic fluid, in a …
This facility tested both steady-state and transient thermal-hydraulic behavior of the fuel asselies. Thermal-hydraulic fuel testing requirements extend beyond the need for CHF characterization, and the Framatome Richland Test Facility has been employed to complete lift-off, pressure drop, and hydraulic characterization of the final fuel design.
17/7/2020· Hydraulic load cells can typically measure up to 5MN and have an accuracy of about 0.25 to 1.0 percent of full-scale output. Their resolution is typically about 0.02 percent. Because these load cells are sensitive to aient pressure, the user must reset the readout to zero before each use.

COBRA-FLX determines in detail the thermal-hydraulic behavior of fuel asselies in the core of pressurized water reactors (PWRs). Thus, operational and safety-related analyses can be performed with high accuracy for homogeneous and mixed cores.
This technique represents the formation material as an assely of discrete particles linked to each other through contacts. Numerical experiments were carried out on two sample materials. For the first instance, tests were carried out on a bulk material, representative of a generic intact rock, with the breakage of inter-particle bonds indiing the formation of cracks.
