The merging of immiscible drops differs significantly from the miscible due to formation a liquid–liquid interface between drops. immiscibility requires four-phase contact point, where drops, gas, and substrate meet. We show that this point has its own unique dynamics, never studied beforehand. For very different scenarios, propagation distance follows scales with time like t12. A model balanci...

Gas–liquid mixtures are present in numerous industrial applications, such as the process industry, oil production and transport with natural gas, deep-sea extraction, irrigation. Any pump may have to carry multiphase flows. However, document is related non-miscible liquid/gas flow analysis centrifugal pumps because which topic can be a more challenging task compared axial mixed machines due spe...

In this study, the comparison and monitoring of the initial greenhouse gas (GHG) emissions using a flux chamber and gas analyzer from three different liquid manure application methods at a swine farm in Kentucky were carried out. Swine slurry was applied to farmland by row injection, surface spray, and Aerway injection. Ammonia and GHG concentrations were monitored immediately after application...

the gas-assisted gravity drainage (gagd) process is designed and practiced based on gravitydrainage idea and uses the advantage of density difference between injected co2 and reservoir oil.in this work, one of iran western oilfields was selected as a case study and a sector model wassimulated based on its rock and fluid properties. the pressure of co2 gas injection was close to themmp of the oi...

1. Introduction The formation of miscible mixtures of two chemically dissimilar polymers is in general unfavourable. For many materials a single phase is never formed, while for others, the miscible state is only obtained at low temperatures. The classic description of the interaction between two polymers is via the Flory-Huggins theory (for example see [l]) in which x, the interaction paramete...

nitrogen oxides (nox) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. in-cylinder high temperature flame and high oxygen concentration are the parameters which affect the nox emissions. the egr system is a very effective way for reducing nox emission from a diesel engine (via reduction of these parameters), particularly at the hi...

Although CO2 injection is one of the most common methods in enhanced oil recovery, it could alter fluid properties of oil and cause some problems such as asphaltene precipitation. The maximum amount of asphaltene precipitation occurs near the fluid pressure and concentration saturation. According to the description of asphaltene deposition onset, the bubble point pressure has a very special imp...

All speed flows and in particular low Mach number flow algorithms are addressed for the numerical approximation of the Kapila et al. [19] multiphase flow model. This model is valid for fluid mixtures evolving in mechanical equilibrium but out of temperature equilibrium and is efficient for material interfaces computation separating miscible and non-miscible fluids. In this context, the interfac...
