Description
|
|
Steady-state solver for 1D turbulent flow, typically to generate boundary
|
|
layer conditions at an inlet, for use in a simulation.
|
|
|
|
Boundary layer code to calculate the U, k and epsilon distributions.
|
|
Used to create inlet boundary conditions for experimental comparisons
|
|
for which U and k have not been measured.
|
|
Turbulence model is runtime selectable.
