Abstract
It is known that for fully developed flows the similarity between heat and momentum transfer can be studied in terms of the temperature and longitudinal velocity fluctuations at a point. Results of spectral and cross-spectral measurements are presented which show that a strong relationship exists between the velocity and temperature field at low wavenumbers but not at high wavenumbers. Considerable flow energy was found associated with wavelengths much larger than the tube diameter and new information about spectral shapes is revealed. From Taylor's hypothesis and time delayed cross-correlations, the streamwise extent of the correlation between the two fields is described.
