There has been an increase in the use of offshore wind farms world wide.These images show the arrangement of the wind turbines near the shore as well as far out in the ocean.Are these arrangements optimal?5Why we need to study offshore wind farmsMotivation for Design

In answering the question are these arrangements optimal we can assume from this image that perhaps they are not. 6Current Wind Tunnel Layout

This is the entire closed loop wind tunnel, jammed into laboratory space on the ground floor of this building.7Test sectionGoal to replace highlighted portion with wave tankCurrent Wind Tunnel Layout
