摘要：

The results of a laboratory experiment to study the spectral density of temperature fluctuations in a fully developed round plume are presented. It is found that there is a range of low wave numbers K (the next to inertial subrange) where the spectra of temperature are proportional to K-3. The modification of turbulent spectrum at small wave numbers due to buoyancy forces in free convection flow is discussed.
