Hi guys. I know turbulence is a b($#H when trying to explain and often poses problems in flyid dynamics. However, our university lecturuer has thrown this at us to think about as it's a pretty interesting topic and I thought there might be some people out there that have ideas about it. The cases he has mentioned include: 1) around a golf ball (separation promotion resulting in speed) and 2) leading edge extensions (suppress stall on aircraft) But he has bonus marks for the person to come up with the best case. ;) I'm thinking biology at lower scales like life science. Possibly turbulence was useful for evolution or growth ect. like plant pollenisation. It's a pretty specialised topic but if any of you guys have some ideas would be cool to hear your thoughts. P.S. I know it comes under HW but thought it might be a cool topic and something I myself find interesting anyway.
