摘要：
The paper is concerned with the statistical study of the dispersion of a cloud of solute injected into a combined free and forced convective laminar flow through a parallel plate channel under the action of a uniform linear axial temperature variation along the channel walls, including the buoyancy forces. The main idea is to study the effect of the Grashof number on the variance, skewness, and kurtosis of the distribution of concentration of the solute for all time. It is found that there is a critical Grashof number for which the distribution of concentration about the mean is exactly a Gaussian function.
