eng.k-epsilon-turbulence-model Calculator
Calculates turbulent kinetic energy, dissipation rate, and turbulent viscosity using the k-ε turbulence model closure equations. The k-ε model is the most widely used in industrial CFD — it performs well for attached boundary layers but poorly for separated flows and strong streamline curvature.
Inputs
K M2 S2
Capacity to do work (J or kWh). Conserved — converts between forms but total stays constant in a closed system.
Eps M2 S3
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Nu M2 S
Fluid resistance to flow. Water at 20°C: ~1 cP. Honey: 2,000–10,000 cP. Higher viscosity increases pumping power requirements.
Cmu
Reference formula or conversion factor shown for context.
