Hi,

If the fluid velocity decreases, will the turbulent flow boundary layer be thicker than before?

Thanks!

Hi,
According to correlations for laminar and turbulent flow over flat plates, V decreases and Re decreases and boundary layer thickness increases.

Delta/x = 5/sqrt(Re); Laminar,
Delta/x = 0.16/(Re^0.1428); Turbulent.

Regards.
