What is the unit of spectral energy?(a) \(\frac{m}{s^2}\)(b) \(\frac{m^3}{s^2}\)(c) \(\frac{m^2}{s^3}\)(d) \(\frac{m^2}{s^2}\)I had been asked this question in an online interview.My question comes from Turbulence Modelling topic in chapter Turbulence Modelling of Computational Fluid Dynamics

Answer»

The CORRECT answer is (B) \(\frac{m^3}{s^2}\)

To explain I would say: Spectral energy is the KINETIC energy per unit mass per unit WAVENUMBER. So, the unit of spectral energy is given by

\(\frac{kg m^2}{s^2}×\frac{1}{kg}×m=\frac{m^3}{s^2}\).
