“…For the low solid fraction arrays, the interaction between the individual wakes and the downstream cylinders is not significant and so it is appropriate to use

ν_{ϵ} = ν

for

R e = 100

(White & Nepf, 2003). For Re > 200 wakes behind cylinders are turbulent (Eames et al, 2011) and therefore for

R e = 333

the effective viscosity was set to

ν_{ϵ} = 5 ν

(White & Nepf, 2003). For low solid fraction arrays setting

α_{ϵ} = 2 ν_{ϵ}

is appropriate (Hinze, 1975).…”

The Transfer and Transport of a Passive Scalar Within an Isolated Array of Circular Cylinders in a Uniform Flow

The transfer and transport of a passive scalar T from an isolated array of circular cylinders of varying Reynolds number (Re = [100, 333]) and solid fraction (0.0023 < < 0.3) in a uniform steady flow are investigated. This problem is an abstraction of the flow past emergent vegetation or marine aquaculture, in which passive contaminants are continuously generated. The upstream flow (T ∞ = 0) is uniform and incident on an array of N c cylinders whose surfaces are set to T S = 1. Three-dimensional numerical simulations were carried out to investigate the mean and fluctuating Nusselt number of the individual cylinders and the array as a whole. To help interpret the numerical results a mathematical model, partly based on empirical relationships, is developed to predict the transfer. The transfer of the scalar from the array was found to increase when the Reynolds number was increased. As the solid fraction is increased the transfer increases, reaches a maximum, and then decreases. This is due to the collective effect of all the cylinders resulting in (i) a modification of the incident flow and (ii) a reduction in the scalar gradient between the cylinder surface and the locally incident flow on individual cylinders. These effects are highly dependent on the solid fraction. Additional simulations were carried out to decompose the contribution of these two processes on the transfer of individual cylinders.
