Document Type: Proceeding Paper

Part of: Fundamentals and Advancements in Hydraulic Measurements and Experimentation


A methodology is described for accurate turbulence measurements with hot film or hot wires even at turbulent intensities as high as 100%. The assumptions involved and the approximations introduced are clearly stated. Corrections to mean velocities due to high turbulence levels are shown to increase with increasing turbulence intensity.
