Q1.
Pitot-probe measurements are taken through a bound-
ary layer at the trailing-edge of a flat plate of length L.
The freestream velocity is U. The boundary layer is
tripped at the leading-edge using a roughness strip to
ensure that the flow is turbulent from the leading-edge.
The y position of the measurement above the wall (in
mm) and measured total pressure P₁ (in Pa) are given
in a .csv file. The static pressure within the wind tunnel
is 101325 Pa. The fluid density and kinematic viscosity
are measured to be p = 1.225 kg/m³, v = 1.5×10−5 m²/s.
data is given in file1 pressure.csv
The
(i) Find the boundary layer thickness, & in mm, which is
defined as the wall-normal position where U
0.99U
(use linear interpolation). Also, find the displacement
thickness of the boundary layer in mm.
=
(ii) What is the total viscous drag per unit span (N/m)
for one side of the entire plate.
