Abstract
The evolution of grid-generated turbulence in a stably stratified flow is experimentally studied to investigate the turbulent structure in which a countergradient heat flux occurs. Simultaneous measurements of the longitudinal and vertical velocities and the temperature are conducted by using the hot-wire anemometer and the cold wire thermometer. The statistics between the velocity fluctuations and the temperature fluctuations are estimated. The experimental results shows that the large-scale wavelike motion dominated the countergradient heat flux in the present air flow.
