Residence time distribution of solid particles in a CSTR

open access: yes, 2002
When mixing in a tank is insufficient solid particles are known to form a concentration gradient along the height. The one-dimensional sedimentation dispersion model provides a relationship between mixing parameters and the solids concentration ...

Various Approaches to Compute Fluid Residence Time in Mixing Systems

open access: yes, 2010
Residence time including mean residence time and residence time distribution (RTD) is a very important parameter to characterize a mixing system. In practice, tracer study has been widely used in experiments to obtain residence time distribution.

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Residence time distribution in tubular reactors

open access: yes
Tema ovog završnog rada bila je odrediti raspodjelu vremena zadržavanja u cijevnim reaktorima. Eksperiment je rađen u tri različite cijevi: praznoj cijevi, cijevi punjenoj staklenim kuglicama i spiralnoj cijevi koja je duža nego prethodne dvije cijevi ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Evaluation of hyporheic zone residence time distribution

open access: yes, 2015
Hyporheic zone (HZ) is the interstitial space immediately below or adjacent to a stream at which there is an active exchange of stream and groundwater.
