Residence time distribution (RTD) revisited. [PDF]

open access: greenChem 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).

Inline Determination of Residence Time Distribution in Hot-Melt-Extrusion. [PDF]

open access: yesPharmaceutics, 2018
In the framework of Quality-by-Design (QbD), the inline determination of process parameters or quality attributes of a product using sufficient process analytical technology (PAT) is a center piece for the establishment of continuous processes as a ...

Subject-Specific Calculation of Left Atrial Appendage Blood-Borne Particle Residence Time Distribution in Atrial Fibrillation. [PDF]

open access: yesFront Physiol, 2021
Atrial fibrillation (AF) is the most common arrhythmia that leads to thrombus formation, mostly in the left atrial appendage (LAA). The current standard of stratifying stroke risk, based on the CHA2DS2-VASc score, does not consider LAA morphology, and ...

Understanding the Residence Time Distribution in a Transient Inline Spiking System: Modeling, Experiments, and Simulations. [PDF]

open access: yesMembranes (Basel), 2023
A transient inline spiking system is a promising tool for evaluating the performance of a virus filter in continuous operation. For better implementation of the system, we performed a systematic analysis to understand the residence time distribution (RTD)

Investigations Concerning the Residence Time Distribution of Twin-Screw-Extrusion Processes as Indicator for Inherent Mixing. [PDF]

open access: yesPharmaceutics, 2018
Over recent years Twin-Screw-Extrusion (TSE) has been established as a platform technology for pharmaceutical manufacturing. Compared to other continuous operation, one of the major benefits of this method is the combination of several unit operations ...

Residence time distribution for a class of Gaussian Markov processes [PDF]

open access: greenPhysical Review E, 1999
We study the distribution of residence time or equivalently that of ``mean magnetization" for a family of Gaussian Markov processes indexed by a positive parameter $α$. The persistence exponent for these processes is simply given by $θ=α$ but the residence time distribution is nontrivial. The shape of this distribution undergoes a qualitative change as

Numerical Analysis of Particle Residence Time Distribution Characteristics in Fluidized Bed Based on Orthogonal Test

open access: green发电技术
ObjectivesThe residence time distribution (RTD) of particles is an important index to evaluate gas-solid mixing degree in fluidized bed, but there are many influencing factors and it is difficult to control.
