I read a post by ceg that says too high of a flow can actually increase the boundary layer https://www.ukaps.org/forum/threads/flow-rates.32752/#post-348211.
"As fluids are put in motion their static pressure decreases and the Boundary Layer thickness becomes thinner up to a certain speed. Above that speed, the Boundary Layer again thickens up. So there is a small range of fluid velocities near the leaf surface where increased flow reduces the thickness of the Boundary Layer and facilitates transport of nutrients/CO2 to the leaf. At velocities below this range the thickness and pressures are high, and above the range the thickness and pressures also increase."
Does anyone know why this happens? Most sources I've read claim an inverse proportion where more flow = less boundary layer.
