Residence time distribution (RTD) revisited. [PDF]
Chem Eng Sci, 2021 Residence Time Distribution (RTD) theory is revisited and tracer technology discussed. The background of RTD following Danckwerts ideas is presented by introducing "distribution" functions for residence time, internal age and intensity function and how to experimentally obtain them with tracer techniques (curves C and F of Danckwerts).

Residence time distribution [PDF]
, 1984 Slurry phase residence time in the SRC-II dissolver is a major process variable affecting the extent of conversion to distillate products. Kinetic studies have shown that overall conversion of vacuum bottoms to lighter hydrocarbons is a zero order process with respect to vacuum bottoms.

Electrochemical Residence Time Distribution as a Diagnostic Tool for Redox Flow Batteries [PDF]
, 2023 The fluid dynamic and electrochemical performance of redox flow batteries (RFBs) stems from the relationship between the flow field and the porous electrode, whose interplay determines how active species move and react during device operation.

Effect of microchannel aspect ratio on residence time distributions and the axial dispersion coefficient [PDF]
, 2009 The effect of microchannel aspect ratio (channel depth/channel width) on residence time distributions and the axial dispersion coefficient have been investigated for Newtonian and shear thinning non-Newtonian flow using computational fluid dynamics.

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

Does residence time affect responses of alien species richness to environmental and spatial processes? [PDF]
, 2012 One of the most robust emerging generalisations in invasion biology is that the probability of invasion increases with the time since introduction (residence time). We analysed the spatial distribution of alien vascular plant species in a region of north-

Residence time in micro-tidal basins [PDF]
, 2022 To evaluate water quality, it is possible to use hydrodynamic indicators, instead of ecological models; the most widely used are some characteristic times-scale. Among them, in this work, residence time is considered.

Bayesian Deconvolution of Vessel Residence Time Distribution [PDF]
International 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.
