Turbulence Inlet Calculator — k, ε & ω
Convert practical inlet turbulence information into k, ε and ω values for RANS boundary conditions in STAR-CCM+, Fluent, OpenFOAM and other CFD solvers.
Use the calculation to challenge the CFD setup.
Turbulence boundary values are often copied from old cases without checking whether intensity and length scale match the inlet-generating geometry. This calculator keeps the assumptions visible.
Define the reference scale. Use values that represent the actual engineering problem.
Calculate transparently. The tool exposes the governing relation and intermediate outputs.
Compare with the solver. Look for inconsistent definitions, units or modelling assumptions.
Test sensitivity. Important CFD conclusions should not depend on one arbitrary input or discretization choice.
Move from calculation to diagnosis.
Use the result as a benchmark, then follow the relevant Technical Case or consulting capability when the actual CFD model needs deeper judgement.
