SCMFrictionMATRA

Class that computes the axial friction factor using the MATRA correlation.

Overview

This class is used to model the axial friction factor for a subchannel assembly with bare fuel pins in a quadrilateral lattice. It implements the MATRA correlation Pang (2014). For Re number ranges: $var element = document.getElementById("moose-equation-0f72f03d-887d-4aeb-99bb-73e144409651");katex.render("0 \\leq Re < 5000", element, {displayMode:false,throwOnError:false});$ where the MATRA correlation is not applicable, a custom model has been applied:

$var element = document.getElementById("moose-equation-4d70826e-550a-4726-91fc-9f2f951e54c4");katex.render("f_w \\rightarrow \\begin{cases} 64, & Re < 1\\\\ \\frac{64}{Re}, &1 \\leq Re<5000\\\\ 0.316 Re^{-0.25}, &5000 \\leq Re < 30000\\\\ 0.184 Re^{-0.20}, &30000 \\leq Re < 1e6 \\end{cases}", element, {displayMode:true,throwOnError:false});$

Input Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:Yes
Description:Set the enabled status of the MooseObject.

Advanced Parameters

prop_getter_suffixAn optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
C++ Type:MaterialPropertyName
Unit:(no unit assumed)
Controllable:No
Description:An optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
use_interpolated_stateFalseFor the old and older state use projected material properties interpolated at the quadrature points. To set up projection use the ProjectedStatefulMaterialStorageAction.
Default:False
C++ Type:bool
Controllable:No
Description:For the old and older state use projected material properties interpolated at the quadrature points. To set up projection use the ProjectedStatefulMaterialStorageAction.
