INSFVOutletPressureBC
This object simply wraps FVFunctionDirichletBC, so a required parameter is function describing the pressure along an outlet boundary. The variable parameter should correspond to the pressure variable. INSFVOutletPressureBC also inherits from INSFVFullyDevelopedBC which allows modifications to the coefficients used to compute the Rhie-Chow interpolation in INSFVMomentumAdvection. When applying a INSFVOutletPressureBC for the pressure, no FVBCs should be given for the velocity on the same boundary. In this way a zero viscous flux is implicitly applied for the velocity on the boundary.
Input Parameters

# 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.
