Miscible viscous fingering occurs when a less fluid displaces more one in porous media or Hele–Shaw cell. Such flow instabilities are of particular interest variety applications flows and displacements subsurface energy environment systems. In this study, we investigate the miscible dynamics experimentally using water to displace glycerol sealed cell with two wells located it instead at boundar...

1, 4-Dioxane is an emerging contaminant a that fully miscible in water and resistant to biodegradation. The presence of vadose zone creates prolonged environmental issues risk human health. To date, treatment technologies for remediation are still being developed. In this work, numeric simulation tool was developed investigate the fate transport enhanced soil vapor extraction (XSVE) which utili...

We calculate the phase diagram of the Bose-Fermi Hubbard model on the 3d cubic lattice at fermionic half filling and bosonic unit filling by means of single-site dynamical mean-field theory. For fast bosons, this is equivalent to the Cooper problem in which the bosons can induce s-wave pairing between the fermions. We also find miscible superfluid and canted supersolid phases depending on the i...

Fractional flow analysis confirms the advantages of surfactant alternative gas injection (SAG) in enhanced oil recovery, but an adsorption phenomenon that has been affected by several factors, weakens the effectiveness of SAG injection. In this study, the effects of sacrificial agent, gas phase, and surfactant concentration on adsorption density on silica mineral were investigated by static and...

Asphaltene deposition is a common phenomenon during CO2 flooding in ultralow permeability reservoirs. The deposited asphaltene occupies the pore volume and decreases permeability, resulting serious formation damage well productivity. It urgent to investigate mechanisms, adverse effects, preventive measures. However, few investigations have been systematically conducted by now. In this research,...

Proper handling of produced sour gas is a big challenge for operating companies due to the serious environmental and technical problems caused by H2S. Among various processing methods, reinjection into reservoirs cost-effective environmentally-friendly technique that not only enhances oil recovery but also allows underground storage The high safety requirements working with toxic H2 S have supp...

We investigate the dynamics of two miscible superfluids experiencing fast counterflow in a narrow channel. The superfluids are formed by two distinguishable components of a trapped dilute-gas Bose-Einstein condensate (BEC). The onset of counterflow-induced modulational instability throughout the cloud is observed and shown to lead to the proliferation of dark-dark vector solitons. These soliton...

I review the methodology of "high-performance" liquid chromatography as applied to therapeutic drug monitoring. Aside from direct injection of sample, sample cleanup involves miscible and immiscible organic solvent extractions, solid-phase extraction, and size separations. Column considerations are bonded phases, column dimensions, particle size, guard columns, stability, pH range, and reproduc...
