# This example demonstrates how the mixing length model can be tuned to match an
# established correlation for pressure drop in a smooth circular pipe.
# The primary input parameters for this example are the system Reynolds number
# and the von Karman constant for the mixing length model. These two parameters
# can be changed here:
Re = 1e5
von_karman_const = 0.22
# Note that for this model (using the wall-distance mixing length for the entire
# pipe) different von Karman constants are optimal for different Reynolds
# numbers.
# This model has been non-dimensionalized. The diameter (D), density (rho), and
# bulk velocity (bulk_u) are all considered unity.
D = 1
total_len = ${fparse 40 * D}
rho = 1
bulk_u = 1
# With those parameters set, the viscosity is then computed in order to reach
# the desired Reynolds number.
mu = ${fparse rho * bulk_u * D / Re}
# Here the DeltaP will be evaluted by using a postprocessor to find the pressure
# at a point that is 10 diameters away from the outlet. (The outlet pressure is
# set to zero.)
L = ${fparse 10 * D}
# We will use the McAdams correlation to find the Darcy friction factor. Note
# that this correlation is valid for fully developed flow in smooth circular
# tubes at 3e4 < Re < 1e6.
f = ${fparse 0.316 * Re^(-0.25)}
# The DeltaP can then be computed using this friction factor as,
ref_delta_P = ${fparse f * L / D * rho * bulk_u^2 / 2}
# The upwind and Rhie-Chow interpolation schemes are used here.
