if the boundary layer on the hood of your car behaves as one on a flat plate, estimate how far from the front edge of the hood the boundary layer becomes turbulent. how thick is the boundary layer at this location?

Sagot :

Far from the front edge of the hood the boundary layer becomes turbulent flow. thick is the boundary layer at this location is 0.052/v.

Renold y number = pvx/μ

for turbulent flow Rc=5*10⁵

5*10⁵=pvx/μ

x=5*10⁵μ/Pv

x=7.306/V

Thickness from blosius equation

=δ/x=s/√Rc

δ=sx/√PVx/μ=5√μx/pv

=5√179*10⁻⁸ˣ7.306/1.125*v²

Thickness=0.052/v.

Laminar flow is a type of fluid (gas or liquid) flow in which the fluid moves in smooth layers or paths while turbulent flow involves irregular fluctuations or mixing. In a turbulent flow, the magnitude and direction of the fluid's speed at a given point are continuously changing.
