“…This occurrence agrees with the trend presented in the literature [10]. On the other hand, the increase in the pH level from pH 4 -8 of a liquid increases the interfacial tension from 2.98 mN/m to 103 mN/m.…”

Abstract.The terminal velocity and the flow behavior of heavy crude oil droplet motion within different aqueous solutions were studied in terms of pH level and aqueous salt concentration. Results showed that the density difference between the oil droplet and the external phase has a significant effect over viscosities and the interfacial tension of each phase. On the other hand, the terminal velocity of oil droplets expresses a negative deviation compared to the theoretical values due to impurities in the aqueous solutions. The present study was conducted for diameters ranging from 5.18 mm to 11.88 mm which resulted in Reynolds number ranging from 590.19 to 1678.18. The transitional phase of deformation for crude oil in pH solutions and salt solutions have been presented as 11-13 mm and 6-8 mm respectively.

“…Water is used as the working fluid in all simulations to represent the aqueous Bromine solution that passes through one side of an H 2 /Br 2 flow battery. Actual electrolyte fluids may have higher viscosities [31,32,33,34], which would further increase the pressure drops presented in this analysis.…”

“…Furthermore, in many flow battery chemistries the viscosity of the electrolyte can be larger than the viscosity of water used in this model [31,32,33,34]. Higher viscosities will further drive pressure losses, and of the large cross channels that transport reactants to and from individual flow channels, is therefore a realistic option for reducing pressure drops in industrially sized, high power designs.…”

The cost of a flow battery system can be reduced by increasing its power density and thereby reducing its stack area. If per-pass utilizations are held constant, higher battery power densities can only be achieved using higher flow rates. Here, a 3D computational fluid dynamics model of a flow battery flow field and electrode is used to analyze the implications of increasing flow rates to high power density operating conditions. Interdigitated and serpentine designs, and cell sizes ranging from 10 cm 2 to 400 cm 2 , are simulated. The results quantify the dependence of pressure loss on cell size and design, demonstrating that the details of the passages that distribute flow between individual channels and the inlet and outlet have a major impact on pressure losses in larger cells. Additionally, in-cell flow behavior is analyzed as a function of cell size and design. Flow structures are interrogated to show how and where electrode parameters influence pressure drops, and how regions where transport is slow are correlated with the presence of experimentally observed cell degradation.

Coupling dispersive liquid-liquid micro-extraction (DLLME) to inductively coupled plasma atomic emission spectrometry (ICP-AES) is usually troublesome due to the limited plasma tolerance to the organic solvents usually employed for metal extraction. This work explores different coupling strategies allowing the multi-element determination by ICP-AES of the solutions obtained after DLLME procedures. To this end, three of the most common extractant solvents in DLLME procedures (1-undecanol, 1-butyl-3-methyl-imidazolium hexafluorophosphate and chloroform) have been selected to face most of the main problems reported in DLLME-ICP-AES coupling (i.e., those arising from the high solvent viscosity and volatility). Results demonstrate that DLLME can be successfully coupled to ICP-AES after a careful optimization of the experimental conditions. Thus, elemental analysis in 1-undecanol and 1-butyl-3-methyl-imidazolium hexafluorophosphate extracts can be achieved by ICP-AES after a simple dilution step with methanol (1:0.5). Chloroform can be directly introduced into the plasma with minimum changes in the ICP-AES configuration usually employed when operating with aqueous solutions. Diluted inorganic acid solutions (1% w w either nitric or hydrochloric acids) have been successfully tested for the first time as a carrier for the introduction of organic extractants in ICP-AES. The coupling strategies proposed have been successfully applied to the multi-element analysis (Al, Cu, Fe, Mn, Ni and Zn) of different water samples (i.e. marine, tap and river) by DLLME-ICP-AES.
