| ConvectionTermReductionCoefficient |
Reduction coefficient for convection terms (kinetic energy terms) in energy equation.
This coefficient is applied when the difference between inflow kinetic energy and outflow kinetic energy

0 corresponds to no reduction (default) whereas 1 corresponds to removing the upstream and
downstream convective terms.
