Boundary Layer Thickness Calculator
Version 1.0.0 (17.2 KB) by
Moreno, M.
Calculates the displacement, momentum, energy and 99% boundary layer thicknesses for compressible and incompressible flow.
THICKNESS(Y,U,R): Calculates the different boundary layer thicknessesfor a rake of coordiantes Y, velocities U, and densities R (optional)in COLUMN form. The integral thicknesses from Schlichting are derivedfrom trapezoidal integrations. The 99% thicknesses are robust metricsfor the standard 'delta99'. Three BL profiles are provided as sample.
INTEGRAL, INCOMPRESSIBLE:
(1) Displacement (incompressible)
(2) Momentum (incompressible)
(3) Energy (incompressible)
INTEGRAL, COMPRESSIBLE
(4) Displacement (compressible: ONLY when R is passed)
(5) Momentum (compressible: ONLY when R is passed)
(6) Energy (compressible: ONLY when R is passed)
GEOMETRIC, ROBUST DELTA 99
(7) 99% variance thickness (4 for incompressible)
(8) 99% asymptotic thickness (5 for incompressible)
If zero outputs are passed, a plot is generated with all thicknesses.If one output is passed, all thicknesses are returned in vector form. If multiple outputs are passed, the indexed thicknesses are returned.

t = thickness(Y,U);
t = thickness(Y,U,R);
t = thickness([Y,U,R]);
[t1,...,tn] = thickness(...);
