Calculators

Estimate the first cell height for viscous sublayer resolution in CFD.

Calculate flow regime and turbulence onset using SI inputs for engineering flow-regime estimates.

Calculate Courant number from SI inputs (velocity, time step, cell size) for CFD stability estimates.

Estimate initial values for turbulent kinetic energy (k), dissipation rate (ε), and specific dissipation (ω) based on empirical correlations.

Quantify numerical uncertainty and verify grid independence in CFD simulations using Roache's methodology.

Estimate laminar and turbulent boundary layer thicknesses over a flat plate for CFD mesh sizing.
