The Ixtapan de la Sal–Tonatico hot springs are located in the geological setting of the Trans-Mexican Volcanic Belt, on the border of the Morelos–Guerrero Basin, which is carbonated region with limestone and silicic rocks. The temperature, electrical conductivity and pH of the thermal waters are 25.7–37.2 °C, 9520–13,920 µS/cm and 5.90–6.88, respec...

In petroleum and mine industries, the centrifugal pumps were used for transferring solid particles with water. This method is preferable to other methods because of its user friendly and economic issues. In this article by selecting a proper pump and designing test circuit, we conducted hydraulic tests for water and water mixture with solid particl...

In this article electrokinetic mixing through heterogeneous microchannels has been studied and the effects of slip coefficient, zeta-potential, Debye–Hückel parameter and Reynolds number on mixing efficiency have been investigated. The microchannels studied here, have non-homogenous zeta-potential distribution at the wall, while other surface prope...

Using first principles electronic structure calculations, we have explored the effects of separate substitutional dopings with Cd/Cr dopants on the structural, mixing and electronic properties of binary CunAg13−n nano-clusters for every possible composition of its two constituents. Both the two classes of the doped CuAg clusters as well as the undo...

This study proposes a secondary flow mixer for neutralizing reagent in a de-ballast pipe. Because the proposed mixer has a U-bent pipe configuration, it can be fabricated using commercially available pipe parts at low cost. Numerical simulations were conducted with four computational domains: one straight pipe (SP) and three U-bent pipes. The norma...
For a fully baffled tank stirred by a Rushton turbine (RT), the flow pattern will change from double- to single-loop as the off bottom dearance (C) of the RTdeaeases from one third of the tank diameter. Such a flow pattern transition as well as its influence on the macro mixing efficiency was investigated via CFD simulation. The transient sliding m...

The aim of this study is to present a novel approach for analyzing the pharmaceutical solid mixing performance of monodisperse particles by a numerical simulation using the mathematical model of rigid solid objects “for a large span of time reached 20 min”. In order to ensure the viability of a numerical simulation, an experimental study of a binar...
The direct quadrature method of moments combined with the interaction by exchange with the mean model (named as DQMOM-IEM) is applied to simulate the novel reactive-PLIF (planar laser induced fluorescence) experiment in an unbaffled stirred reactor. By using the mixture fraction and reaction progress variables, the descriptions of the Fenton reacti...
