Flow between two concentric cylinders, with either or both of them rotating, has potential advantages over the conventional process equipment. This flow, which is also termed Taylor−Couette flow and exhibits a variety regimes, been studied using computational fluid dynamics (CFD) simulations. The onset centrifugal instability, various cell patterns, velocity profiles have predicted compared available experimental data. To extend base information, new measurements made laser Doppler...

Annular centrifugal extractors (ACE), also called annular contactors offer several advantages over the other conventional process equipment such as low hold-up, high throughput, residence time, solvent inventory and turn down ratio. The provides a very value of mass transfer coefficient interfacial area in zone because level power consumption per unit volume separation inside rotor due to g field. For development rational reliable design procedures, it is important understand flow patterns...

Flow between two concentric cylinders, with either or both of them rotating, has potential advantages over the conventional process equipment. This flow, also termed as Taylor−Couette which reveals a variety flow regimes, is studied using computational fluid dynamics (CFD) simulations. The vortex motion causes mixing in annulus, necessitates understanding residence time annulus and time. A systematic study distribution (RTD) phenomenon annular region contactor been carried out. RTD...

Abstract Two‐fluid Taylor‐Couette flow, with either one or both of the co‐axial cylinders rotating, has potential advantages over conventional process equipment in chemical and bio‐process industries. This flow been investigated using three‐dimensional CFD simulations. The occurrence radial stratification, subsequent onset centrifugal instability each phase, cell formation dependency on various parameters have analyzed discussed. criteria for Taylor phase established. It can be stated that...

The overall performance of a wastewater treatment plant is in addition to the effectiveness biokinetic processes controlled by flow dynamics. A wide used technique characterize water dynamics use tracers. At full-scale tracer experiments plants provide insufficient information completely grasp Additionally results are often biased uncontrolled external factors. As alternative, computational fluid dynamic (CFD) models for analysis existing and design new have been increasingly over last...

Time-dependent laminar flow in a continuous fluidic oscillatory reactor was studied using computational fluid dynamics (CFD). Single-phase CFD models are developed for both the (C-OFR) and (F-OFR), to analyze patterns regime. Fluid C-OFR F-OFR is entirely different, even though driven by flows. This due difference nature of oscillations imparted, longitudinal, transverse oscillations, respectively. The effect caused baffles upon pressure drop, as well instantaneous shear strain rate fields...

Over the past few decades, Computational Fluid Dynamics (CFD) has emerged as a powerful tool for design and optimization of new products processes. It is widely used in variety applications industries such chemical, petroleum, aerospace, automotive, power generation, polymer processing, medical research, construction, meteorology, so forth. Some key offerings include reliability reduction time cost product development. A signi�cant research being carried out quest to model physics accurately...

Recovery of chlorine from byproduct HCl has inevitable commercial importance in industries lately because insufficient purity or too low concentration to recycle it. Instead it is being neutralized before disposing meet stringent environmental conditions. Although recovery through catalytic oxidation processes studied since the 19th century, their high operating conditions combined with sluggish reaction kinetics and single pass conversions make electrolysis a better alternative. The present...

Abstract Superimposition of oscillatory flow over the axial is expected to further enhance mixing phenomenon based on limited reported literature. A detailed study physics such superimposed flows will be useful widen scope application static mixers with in continuous modes operation for several purposes.
