K_Factor

Syntax

Bc Bulknode_Flux For Mass_Balance ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} Mesh Extent Name ([Touching TouchingMeshExtent] | [Opposing OpposingMeshExtent]) = K_Factor [Using Data Specification Data Spec Name] (Bulk_Node = bulk_node | [Flow_Rate_Limiter = flow_rate_limiter])

Summary

Volumetric flow rate, Q, calculated as Q = K \sqrt{\frac{P_{high} - P_{low}} {\rho} }. Absent any other sources, the maximum flow rate is defined based on the mass loss to achieve pressure equilibrium and the fluid time step. If the optional flow rate limiter is specified, the flow rate is limited by the product of the limiter factor and the maximum flow rate without any other sources.
