Abstract

Abstract: Measurements of the longitudinal velocity fluctuation u and of the temperature fluctuation θ in a turbulent boundary layer indicate a strong correlation between u and θ in the immediate vicinity of the wall, the absolute value of the correlation coefficient approaching unity at the wall. The importance of low-speed or high-temperature streaks is examined and quantified by considering joint probability and spectral density functions of u and θ.
