This model defines the pressure loss assuming turbulent flow for
specified dp_nominal
and m_flow_nominal
.
It takes into account the fluid density of each flow segment and
obtains appropriate pathLengths_nominal
values
for an inverse parameterization of the
TurbulentPipeFlow
model. Per default the upstream and downstream densities are averaged with the setting useUpstreamScheme = false
,
in order to avoid discontinuous pathLengths_nominal
values in the case of flow reversal.
The geometry parameters crossAreas
, diameters
and roughnesses
do
not effect simulation results of this nominal pressure loss model.
As the geometry is specified however, the optionally calculated Reynolds number as well as
m_flows_turbulent
and dps_fg_turbulent
become meaningful
and can be related to m_flow_small
and dp_small
.
