The present work involves measurements to examine the effects of initial conditions on aerodynamic and acoustic characteristics of a Jet at M=0.8 by changing the orientation of sharp edged orifice plate. A thick plate with chamfered orifice presented divergent and convergent openings when it was flipped over. The centerline velocity was found to decay more rapidly for divergent orifice and that...

A Laser Induced Fluorescence technique (LIF) has been used to study the mixing behavior of two emerging streams in a T-Type mixing chamber. A mixing index on the basis of digital image light intensities is calculated. It has been shown that averaging over more than 800 images leads to a stable mixing index calculation. Moreover, the effect of equal and un-equal flow rates on the mixing behavior...

In-situ NMR spectroscopic analysis of homogeneous reactions is an essential tool for mechanistic in organic and organometallic chemistry. However, rapid non-equilibrium reactions, that are initiated by mixing, require specialized approaches. We report herein on a study the factors ensure quantitative results recently-developed technique stopped-flow spectroscopy. The influence some key paramete...

For the A = 32, T = 2 quintet we provide a unified theoretical description for three related aspects of isospin mixing: the necessity of more than three terms in the isobaric mass multiplet equation, isospin-forbidden proton decay in 32Cl, and a correction to the allowed Fermi β+ decay of 32Ar. We demonstrate that all three effects observed in experiment can be traced to a common origin related...

Stirred tank reactors are one of the most commonly used equipments in industry for achieving mixing and reaction. Flow fields in a stirred reactor are obtained via computational fluid dynamics. In this work CFD is used for the simulation of a reactive flow process consisting of a second order reaction. The extent of reaction is found to depend on impeller speed and its position from the bottom ...

In this work, we report about the mechanical relaxation characteristics of an intrinsically self-healable imidazole modified commercial rubber. This kind of self-healing rubber was prepared by melt mixing of 1-butyl imidazole with bromo-butyl rubber (bromine modified isoprene-isobutylene copolymer, BIIR). By this melt mixing process, the reactive allylic bromine of bromo-butyl rubber was conver...

Transported chemical reactions in unsaturated porous media are relevant to environmental and industrial applications. Continuum scale models based on equivalent parameters derived from analogy with saturated conditions cannot appropriately account for incomplete mixing. It is also unclear how the third dimension controls mixing reactions. We obtain three-dimensional (3D) images by magnetic reso...
