Gas–liquid flow generated by a Rushton turbine in stirred vessel: CARPT/CT measurements and CFD simulations
TL;DR: In this paper, computer-automated radioactive particle tracking (CARPT), computed tomography (CT) and computational fluid dynamic (CFD) based models were used to investigate gas-liquid flow generated by a Rushton turbine.
Journal ArticleDOI
Effect of inert solid particles at low concentrations on gas-liquid mass transfer in mechanically agitated reactors
TL;DR: In this paper, the volume referred mass transfer coefficients k L a were determined for the slurries of 6 solids in water and n -butanol in a mechanically agitatted reactor of standard configuration.

David L. Trent,Quarderer George J,Kim G. Bargeron,Douglas C. Greminger,David J. Koranek,Erik J. Stewart,Curtis N. Swisher,Cheryl A. Tirtowidjojo,Danil Tirtowidjojo +8 more
TL;DR: A process of preparing alkylene oxides comprises steps of: (1) optionally contacting metal hydroxide or oxide with chlorine to form a metal hypochlorite solution; (2) contacting chlorine with a solution of a metal hyper-chlorite at a temperature below 60 °C, and a pH of less than 5.5, with sufficient micromixing to achieve a product hypochchlorous acid in a yield of at least 80 mole percent based on hypochemically defined alkylorite; (3) separating at least a portion of the hyp

Dynamics of Flow Structures and Transport Phenomena, 2. Relationship with Design Objectives and Design Optimization
TL;DR: There have been several approaches in the literature to identify and characterize flow structures qualitatively as well as quantitatively as discussed by the authors, and a stepwise procedure is suggested for the design of equipment using flow structure knowledge, where an attempt has been made to relate the structure properties (such as age, penetration depth, size, shape, and energy content distribution) to the design parameters, such as mixing time, heat and mass-transfer coefficient, drag coefficient, dissipation rate, etc.).
Journal ArticleDOI
A theoretical and experimental study of hyperbolic and degenerate mixing regions in a chaotic Stokes flow
TL;DR: In this article, the authors examined the rotor-oscillator flow, a slow viscous flow between long parallel plates driven by the rotation of a slender cylinder (the rotor) and the longitudinal oscillation of one of the plates (the oscillator).

Fundamentals of the hydrodynamic mechanism of splitting in dispersion processes
TL;DR: In this paper, Taylor's experiments on the breakup of a drop in simple types of viscous flow, (b) breakup of an air stream, and (c) emulsification in a turbulent flow are studied.

Design parameters estimations for bubble column reactors
TL;DR: In this article, the present state-of-the-art for the estimation of nonadjustable parameters in bubble column reactors is evaluated and a discussion is followed by relevant recommendations for their predictions.
Journal ArticleDOI
Agitation of non‐Newtonian fluids
TL;DR: In this article, a general relationship between impeller speed and the shear rate of a non-Newtonian fluid has been developed, and the resulting relationship was then used to interpret and correlate power-consumption data on three non-newtonian fluids by use of a generalized form of the conventional power-number-Reynoldsnumber plot for Newtonians.
Journal ArticleDOI
Suspending of solid particles in liquid by agitators
TL;DR: In this paper, an investigation of the required stirrer speed and stirrer dimensions for the suspending of solid particles in a low viscosity liquid has been carried out and the results are given in dimensionless form.

The continuous phase heat and mass transfer properties of dispersions
P.H. Calderbank,M.B. Moo-Young +1 more
TL;DR: In this paper, the authors measured the interfacial area in gas-liquid dispersions and correlated the data with other published data for heat and mass transfer in liquid-liquid and solid-gas dispersions in which the dispersed phases are free to move under the action of gravity.
