Turbulence degree

Air velocity in indoor areas directly affects thermal comfort. The turbulence is given as a percentage, calculated from the mean air velocity and air temperature in indoor areas. The turbulence indicates the air velocity fluctuation and intensity of air flow in an indoor area. There is a direct correlation between the air temperature and turbulence measured.
