Shale gas is a major component of the hydrocarbon economy, and there are abundant studies in related exploration exploitation fields using simulations experiments. In this paper, kinetic processes adsorption displacement during shale analyzed enthalpy-driven entropy-driven with molecular dynamics statistical mechanics analyses. First, changes symmetry CH 4 CO 2 adsorbed on graphene surface anal...

Unsynchronised, dry-running screw machines have advantages compared to conventional oil-injected and synchronised, machines. Because of the absence an additional timing gear no injected lubricant, effort for manufacturing assembly can be reduced lubricant residues in process gas are avoided. In this design female rotor torque resulting from pressure is transferred directly male by contacting su...

An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...

A major challenge for modern steelmaking is the reduction of CO2 emissions. In this regard, blast furnace (BF) process critical due to its high associated This investigation assesses impact tuyere-injected fuels on BF Specifically, CFD results obtained previously at Purdue University Northwest are analyzed obtain emissions when natural gas (NG), syngas, hydrogen or hydrogen/NG injected. compare...

Abstract We present here a numerical model of planar magnetron with electron injection from the plasma an auxiliary discharge hollow cathode. The is based on solving system stationary equations using method successive approximations. takes into account effects current injected electrons, operating gas pressure, magnetic field induction, flow target material plasma, and change in mass-to-charge ...

CO2-based enhanced gas recovery (EGR) is an appealing method with the dual benefit of improving from mature reservoirs and storing CO2 in subsurface, thereby reducing net emissions. However, injection for EGR has drawback excessive mixing methane gas, therefore, quality produced leading to early breakthrough CO2. Although this issue been identified as a major obstacle EGR, few strategies have s...
