Distribution and Expected Time of Residence for U.S. Households

Risk Analysis, 1992
For risk assessments, the average current residence time (time since moving into current residence) has often been used as a surrogate for the average total residence time (time between moving into and out of a residence). Since the distributions of the two quantities are not necessarily the same, neither are their averages.

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 Distribution of a Cylindrical Microreactor

The Journal of Physical Chemistry B, 2005
The residence time distribution for the flow of liquid reactants containing electrolytes in a cylindrical microreactor is derived under the conditions of constant surface potential and negligible end effects. The influences of the key parameters, including the thickness of the double layer, the strength of the applied electric field, and the magnitude ...

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.

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.
