eng.reynolds-averaged-turbulence Calculator
Calculates Reynolds-averaged turbulence intensity (u'/U) from velocity fluctuation data and evaluates against design criteria. Turbulence intensity of 1–5% is typical in open-air environments; 10–20% in wakes and near walls — this affects fatigue loading on structures in wind.
Inputs
Mean Velocity M S
Speed in a specified direction (m/s). Required for momentum, kinetic energy, and wave calculations.
Turbulent Kinetic Energy M2 S2
Capacity to do work (J or kWh). Conserved — converts between forms but total stays constant in a closed system.
Turbulent Length Scale M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Results
turbulence intensity I
Sample size or count used in the calculation.
turbulent dissipation ε (m²/s³)
The value at the specified point or condition.
specific dissipation omega (1/s)
The value at the specified point or condition.
TKE k
Reference formula or conversion factor shown for context.
intensity classification
Category assigned based on where the computed value falls on a defined scale. Check which standard or guideline defines these boundaries.
