An understanding of the statistics of concentrations of chemical tracers dispersing through multicompartment structures such as buildings, ships, and aircraft is important in many applications (e.g., industrial, military, and ecological). Such an understanding can be useful for early detection of hazardous releases, source backtracking, and assessment of their impact on engineered structures (e.g., buildings, aircraft, ships). It may be also important for design of monitoring sensor systems. We present the statistics of chemical tracer concentrations obtained by analysing recent experimental data obtained in a study of tracer dispersion in a complex structure. The experiment involved the release of a tracer (dyed salt solution) from a point source placed inside a multi-compartment structure (Fig. 1) embedded in a water tank and measuring the salt concentration at different locations within the compartments using a network of conductivity sensors. We show that moments of measured concentration at a given sensor depend on the Euclidean distance between the source and the sensor, resembling the behaviour observed in advection-diffusion transport in porous media.

The experimental setup: (a) Image of the multi-compartment structure used for the experiment; (b) the flow path in the OPEN configuration; and, (c) the flow path in the CLOSE configuration.
