摘要：
Initially homogeneous and isotropic turbulence with velocity and passive scalar fluctuations is submitted to solid-body rotation. It is shown, using the basic equations, that triple correlations between two components of the scalar gradient and vorticity appear. A phenomenological and order-of-magnitude analysis is proposed.
