1 A large-eddy simulation study of wake propagation and power production in an array of tidal-current turbines by Matthew J. Churchfield, Ye Li, and Patrick J. Moriarty Philosophical Transactions A Volume 371(1985):20120421 February 28, 2013 ©2013 by The Royal Society

2 Plan view of tidal turbine array in (a) non-staggered and (b) staggered configuration. Matthew J. Churchfield et al. Phil. Trans. R. Soc. A 2013;371:20120421 ©2013 by The Royal Society

3 (a) Mean horizontal velocity and (b) variance profiles of tidal channel precursor flow. Matthew J. Churchfield et al. Phil. Trans. R. Soc. A 2013;371:20120421 ©2013 by The Royal Society

4 One-dimensional spectra taken in the streamwise direction of (a) horizontal velocity and (b) vertical velocity at various heights. Matthew J. Churchfield et al. Phil. Trans. R. Soc. A 2013;371:20120421 ©2013 by The Royal Society

5 Contours of instantaneous resolved velocity normalized by hub-height velocity on horizontal planes. Matthew J. Churchfield et al. Phil. Trans. R. Soc. A 2013;371:20120421 ©2013 by The Royal Society

6 Instantaneous view of the flow field from case J with staggered counter-rotating turbines. Matthew J. Churchfield et al. Phil. Trans. R. Soc. A 2013;371:20120421 ©2013 by The Royal Society

7 Instantaneous contours of (a) resolved streamwise velocity and (b) resolved vertical velocity in a horizontal plane at the turbine hub height from case B. The flow is from left to right, the black vertical lines denote the location of the rotor discs, and t... Matthew J. Churchfield et al. Phil. Trans. R. Soc.
