Hot-wire corrections at a high turbulence level
Abstract
A systematic error in measurements conducted with a hot-wire anemometer is related to the directional insensitivity of the hot wire with respect to the flow velocity in the normal plane perpendicular to the axis. The significance of this error source is investigated. It is found that in many flow problems the values obtained for the mean flow velocity are too high and the data for the effective value of the turbulence are too low.
