A neatly aligned laminar ?ow around a wing of an aircraft giving enough lift, can become highly irregular and separatedfrom the surface,with the result of a loss of lift. For cooling of - gines of transportand other systems highly irregular turbulent ?uid ?ows across the components are needed to guarantee a large heat transfer.
