Temperature is an important parameter in most high speed flow experiments, but it is sometimes a difficult parameter to measure, particularly in short-duration facilities. Stagnation temperature measurements have been obtained using transient thin film he

A wedge-shaped hot-film probe is used to perform measurements of turbulence intensity and an estimate of the turbulent kinetic energy as well as the Eulerian spectra, macro- and micro-scales of the gas phase in a horizontal pipe flow carrying pulp fibres or spherical particles. In addition, the paper gives a summary of a method for handling the poor frequency response of the probe and discusses how to sort out “bad samples”, occurring when the probe is hit by particles.
