In order to capture an economically significant amount of energy,
arrays of tidal turbines will need to increase in size from
present test deployments. Once these arrays reach a large size, they
change the large-scale flow characteristics of the channel they are
deployed in. Most previous studies of power capture in arrays
implicitly apply to small arrays because they impose a fixed freestream
velocity at open boundaries. Garret and Cummins developed
an analytical model that assesses a turbine in a channel [1].
This analytical model was extended to apply to a single, small,
packed rowof turbines in a wide channel by Ref. [2]. Small arrays of
idealised turbines have previously been modelled in 2-D or 3-D
using a range of turbine representations. Idealised drag elements,
Blade Element Momentum Theory, fixed rotor, rotating line
