Abstract:

The hydrodynamic characteristics of bodies are greatly affected by cavitation. Coupling with natural cavitaion model, a multiphase CFD method is developed and is employed to simulate supercavitating and partial cavitating flows over axisymmetric bodies using FLUENT 6.2. The results of supercavitation of a disk cavitator agree well with the boundary element method (BEM), the analytical relations and available experimental results. The present computations and the BEM results are compared with experiments for partial cavitating flows over three typical axisymmetric bodies and the results are dis

Abstract:

Drinking water quality is an acute problem all over the world. Unauthorized discharges of contaminated wastewater into life-sustaining water sources make the latter undrinkable. The Ganges River is the main artery of India’s economic and domestic use with the numerous industries located on its banks. This paper is devoted to studying the possibility of improving the quality of drinking water in the Ganges River, India. The studied water is already chemically and microbiologically contaminated at the entrance to the city. The hydrodynamic method of water treatment using ozone in small doses is

Abstract:

Cavitation-erosion is a hydrodynamic phenomenon that results in the formation and collapse of vapor bubbles in a liquid. Cavitation damage is encountered in a wide variety of fluid handling machinery and over a broad range of liquid pressures and temperatures. In this study, cavitation damage was investigated by using the piezoelectric vibrator with 20kHz, 50μm to cavity generation apparatus. At the first cavitation test, coated composite material specimens appear to generating the low bubbles due to damping vibration. This study is mainly compared with cavitation test (ASTM G 32) and modified

Abstract:

Biodiesel emerges as a viable option to replace fossil fuels, but the traditional process for the production of biodiesel requires a large energy expenditure, since transesterification has a slow conversion due to the immiscibility of alcohol and oil. On the other hand, with the hydrodynamic cavitation method, a shorter conversion time can be achieved with a high yield; however, there are few studies related to this method. Therefore, the objective of this article is to analyze information from different scientific publications to compare and visualize the parameters used to obtain biodiesel b

Abstract:

Single-wall carbon nanotubes (SWCNTs) are promising materials for electronic applications, such as transparent electrodes and thin-film transistors. However, the dispersion of isolated SWCNTs into solvents remains an important issue for their practical applications. SWCNTs are commonly dispersed in solvents via ultrasonication. However, ultrasonication damages SWCNTs, forming defects and cutting them into short pieces, which significantly degrade their electrical and mechanical properties. Herein, we demonstrate a novel approach toward the large-scale dispersion of long and isolated SWCNTs by

A new method for the synthesis of complex metal oxides, based on hydrodynamic cavitation, was used to prepare pure phase, nanostructured solid-state materials. The continuous process afforded a wide variety of metal oxides in grain sizes of 1-10 nm. Catalysts, ceramics, superconductors, piezoelectrics, and zeolites were prepared by cavitational synthesis. The method enabled the synthesis of fine particles of metals and metal oxides supported on high surface area supports such as silica, and the synthesis of fine particles of cubic zirconia without ion modification.

The possibility of using hydrodynamic cavitation to intensify the synthesis of solketal from glycerol and acetone in the presence of zeolite has been demonstrated for the first time. The reaction was studied in the presence of faujasite zeolite (FAU, SiO2 /Al2O3 = 14.9). It was found that the use of hydrodynamic cavitation promotes an increase in glycerol conversion from 35.2 to 66.8% in 30 min of reaction without changing the selectivity for solketal at an acetone/glycerol molar ratio of 2.5, a catalyst load of 1.6 wt.% (based on the weight of loaded glycerol) and 25 °C.
