Experimental Study on the Solids Residence Time Distribution in Multiple Square-Based Spouted Beds

open access: yesEnergies, 2020
The present work aims at investigating the residence time distribution (RTD) of a multiple spouted bed reactor, which will be applied for the pyrolysis and gasification of residual biomass.

Residence-time distributions for chaotic flows in pipes [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 1999
In this paper we derive two rigorous properties of residence-time distributions for flows in pipes and mixers motivated by computational results of Khakhar et al. [Chem. Eng. Sci. 42, 2909 (1987)], using some concepts from ergodic theory. First, a curious similarity between the isoresidence-time plots and Poincaré maps of the flow observed in Khakhar ...

Residence Time Distribution (RTD) Applications in Continuous Casting Tundish: A Review and New Perspectives

open access: yesMetals, 2022
The continuous casting tundish is a very important metallurgical reactor in continuous casting production. The flow characteristics of tundishes are usually evaluated by residence time distribution (RTD) curves.

Residence time distributions for in-line chaotic mixers

open access: yesPhysical Review E, 2022
We investigate the distributions of residence time for in-line chaotic mixers; in particular, we consider the Kenics, the F-mixer and the Multi-level laminating mixer, and also a synthetic model that mimics their behavior and allows exact mathematical calculations.

Bayesian Deconvolution of Vessel Residence Time Distribution [PDF]

open access: yesInternational Journal of Chemical Reactor Engineering, 2017
Abstract Residence time distribution (RTD) within vessels is a critical aspect for the design and operation of continuous flow technologies, such as hydrothermal synthesis of nanomaterials. RTD affects product characteristics, such as particle size distribution.

Spatial aggregation effects on the performance of machine learning metamodels for predicting transit time to baseflow

open access: yesEnvironmental Research Communications, 2023
Water transit time is the duration between the entry and exit of a parcel of water across a hydrologic system. It is a fundamental characteristic that links hydrologic transport, biogeochemical processing, and water quality, and it has broad implications

Numerical Investigation of the Hydrodynamic Conditions in A Multi-Strand Cc Tundish with Closed Outlets

open access: yesArchives of Metallurgy and Materials, 2014
In industrial conditions there are situations when the CC machine works under emergency. It can be result of mechanical or electrical causes, breakout of billet or problem with supplying new parts of liquid steel to the CC machine.
