SPECTRAL ANALOGY BETWEEN TEMPERATURE AND VELOCITY FLUCTUATIONS IN SEVERAL TURBULENT FLOWS.

Author(s) : FULACHIER L., ANTONIA R. A.

Type of article: Article

Summary

THE ANALOGY ESTABLISHED BY FULACHIER AND DUMAS IN THE CASE OF A TURBULENT BOUNDARY LAYER WITH ZERO PRESSURE GRADIENT OVER A UNIFORMLY SLIGHTLY HEATED SURFACE, IS TESTED IN DIFFERENT TURBULENT FLOWS. THESE FLOWS INCLUDE A BOUNDARY LAYER SUBJECTED TO THE SUDDEN APPLICATION OF WALL SUCTION, A MODERATELY UNSTABLE BOUNDARY LAYER OVER A ROUGH WALL, THE ATMOSPHERIC SURFACE LAYER AT VERY HIGH REYNOLDS NUMBERS AND WITH DIFFERENT STABILITY CONDITIONS, A PLANE JET, A PLANE WAKE AND NEARLY HOMOGENEOUS TURBULENCE WITH UNIFORM MEAN VELOCITY AND MEAN TEMPERATURE GRADIENTS. THE ANALOGY WORKS WELL EXCEPT IN THE ATMOSPHERIC SURFACE LAYER WHEN CONDITIONS BECOME INCREASINGLY STABLE.
