Flow uniformity index formula
WebTurbulent kinetic energy is the quantitative measure of the intensity of turbulence for a given flow. It can be measured as the root mean square of the fluctuation in flow velocity. In fluid dynamics, it can simply be defined as the mean kinetic energy per unit mass for a turbulent flow. Mathematically, kinetic energy can generally be expressed ...
