From the commercial point of view it may be beneficial to installa set of marine current turbines forming a park, by analogy with windparks. Consequently, this motivates research on park configurations.An array of ten vertical axis marine current turbines is simulatedto study how the distance between the turbines affects the performanceof the park for different flow directions. The simulations are performedusing a two-dimensional vortex method. An array of identical turbinesis created, where all turbines are on a single line. The turbinesare operated at the tip speed ratio, which corresponds to the highestpower coefficient for a single turbine. The distance between the turbinesis varied and the total power from the array is compared to the turbinespacing for different flow directions.Additionally, flow data from a real site is used to find an optimalorientation of the line of turbines. The performance of the arrayis estimated for the site as a function of turbine spacing.
