Abstract
Statistics of temperature fluctuations were measured in uniformly sheared turbulence with a uniform mean temperature gradient. The scalar pdf was Gaussian and the scalar-velocity joint pdf was jointly Gaussian, with the conditional expectations of the velocity fluctuations linearly dependent on the scalar value. The scalar dissipation rate was statistically independent from the scalar value. A Gaussian scalar pdf was also predicted analytically.
