Abstract: Measurement of temperature distribution, thermal diffusivity and temperature fluctuations have been made in a uniform turbulent flow with a step change in temperature. It is found that the spread of temperature is described by a constant diffusion coefficient which when related to the local turbulence properties compares well with measurements in the core region of open channel flow.
