内容記述 | This study aims to clarify the relation between the occurrence of counter-gradient heat flux and the spatial structure of internal gravity waves in a strongly stably-stratified mixing layer. Multi-point simultaneous measurement of temperature and velocity field was conducted by a rake of 7 cold- and hot-wires. The aspect of streamwise change in temperature spectrum showed that the internal gravity waves with fundamental frequencies of 1.2, 1.8, 3.0 Hz developed in the mixing layer and suddenly collapsed in the downstream region. As the amplitude of the waves increased downstream, coherence became larger among the temperature signals given by the cold-wire rake. When the internal gravity waves broke down at their wave front, counter-gradient heat flux occurred through the nonlinear interaction among the fundamental frequencies and their higher harmonics. | |||||
