Deformation behaviour of leaves will be explored using the wind tunnel at Brunel University with the aim of optimising leaf shape and aspect ratio . This will include a preliminary investigation of drag forces of the solar collector leaves in the wind tunnel. Existing IP on similar biomimetic technologies will be reviewed to optimise performance.
