Random residence time distribution

Chemical Engineering Science, 1986
Abstract A discrete stochastic mixing model for chemical reactors is presented. The model is particularly useful to study the statistics of RTD and of the output concentration in a chemical reactor. Some computations of confidence intervals of concentration using information about the stochastic nature of flow are presented.

Residence time distribution in kneading extruders

Journal of Food Engineering, 1995
Abstract The residence time distribution (RTD) of a kneading extruder processing a food material is measured with a lithium tracer. The curve width of the measured RTD curves is comparable with that of co-rotating, twin-screw extruders. Except for the tail, the extinction curve of the filled part of the extruder can be described reasonably with a ...

RESIDENCE TIME DISTRIBUTIONS FOR DOUBLE-SCROLL ATTRACTORS

International Journal of Bifurcation and Chaos, 2007
We investigated a choice of prototypical double-scroll attractors, namely trajectories resulting from Lorenz equations and from two sets of equations related to Chua's circuits. We found that the probability distribution for the residence times within a given scroll consists of prominent, exponentially decaying peaks.

Wetland residence time distribution modeling

Ecological Engineering, 2000
Abstract The non-ideal flows of constructed wetlands were modeled with a network of an infinite number of small stirred tanks distributed along a set of main plug flow channels. The stirred tanks represent zones of diminished mixing (ZDMs) because they undergo only limited exchange of water with the main channels.
