Abstract In the present paper, an enhanced Volume of Fluid model is applied for conduction parametric numerical simulations, to investigate break-up phenomena accelerating, elongated, vapour bubbles, within circular mini-channels. The effect fundamental controlling parameters in resulting characteristics investigated. Four different series simulations isolated bubbles mini-channels are performe...

Almost 40% of undiscovered hydrocarbon reserves have high CO2 and H2S concentrations around the globe. So it is crucial to understand these systems’ thermophysical properties for excellent design production facilities. An experimental investigation conducted in this study evaluate thermodynamic conditions gas hydrate formation natural systems with levels dominant multiphase (high level gases, d...

Solar energy is the most abundant source of energy available in our country. The power of the sun can be efficiently used to harness energy for solving our energy needs. The void of not having efficient technology to tap this abundant energy reservoir has led to search for better technologies and more varied applications. Our primary focus in this paper would be on utilizing solar energy for do...

The huge number of possible combinations of binary mixtures of alcohols and ionic liquids (ILs) make the exhaustive measurement of all these ystems impracticable requiring the use of a predictive model for their study. In this work, the predictive capability of COSMO-RS, a model based n unimolecular quantum chemistry calculations, was evaluated for the description of the liquid–liquid equilibri...

The formation of gas hydrates is a major issue during the operation oil and pipelines, because cause plugging, thereby disrupting normal flows. A solution to inject hydrate inhibitors such as ionic liquids. Contrary classical inhibitors, liquids act both thermodynamic anti-agglomerates. Imidazolium-based have been found efficient for inhibition CO2 CH4 hydrates. For hydrates, N-ethyl-N-methylmo...

Potassium carbonate (K2CO3) is a promising thermochemical heat storage material (TCM). However, it suffers from hysteresis between (de)hydration temperatures and poor reaction kinetics close to equilibrium conditions. Both aspects are caused by nucleation barrier low ionic mobility equilibrium. This study investigates the impact of caesium fluoride (CsF) incorporated through recrystallisation o...

Abstract This paper presents simulations of the growth stationary and rising vapour bubbles in an extend pool liquid using Interface Capturing Computational Fluid Dynamics (CFD) methodology coupled with a method for simulating interfacial mass transfer at vapour-liquid interface. The model enables mechanistic prediction local rate phase change interface is applicable to realistic cases involvin...

The development of non-equilibrium group IV nanoscale alloys is critical to achieving new functionalities, such as the formation of a direct bandgap in a conventional indirect bandgap elemental semiconductor. Here, we describe the fabrication of uniform diameter, direct bandgap Ge(1-x)Sn(x) alloy nanowires, with a Sn incorporation up to 9.2 at.%, far in excess of the equilibrium solubility of S...
