Sinopsis

Extensive measurements were made of the response of a turbulent boundary layer to a double step change of wall heat flux. The measurements include mean temperature and velocity as well as temperature-velocity correlations up to third order occuring in the ν2 and vν transport equations together with the skewness and flatness of temperature fluctuations. Two internal thermal layers start to develope from the points where the boundary conditions abruptly change, having quite different growth rates which found to depend on the wall heat flux as well. Most of the changes in the downstream stations take place inside the second thermal layer.
