Some Corrections to the Linearized Response of a Constant-Temperature Hot-Wire Anemometer Operated in a Low-Speed Flow

Abstract

An equation is obtained for the instantaneous response of a constant-temperature hot-wire anemometer having a linearized output. The result includes the second-order effects of variations in fluid temperature and in flow direction. Corrected equations for outputs in terms of mean velocity, turbulent-intensity components, and shear stress are derived from the instantaneous response.
