The turbulent Prandtl number is a non-dimensional term defined as the ratio between the momentum eddy diffusivity and the heat transfer eddy diffusivity. It is useful for solving the heat transfer problem of turbulent boundary layer flows. The simplest model for is the Reynolds analogy, which yields a turbulent Prandtl number of 1. From experimental data, has an average value of 0.85, but ranges from 0.7 to 0.9 depending on the Prandtl number of the fluid in question.

Famous quotes containing the words turbulent and/or number:
“Who ever hears of fat men heading a riot, or herding together in turbulent mobs?—No—no, ‘tis your lean, hungry men who are continually worrying society, and setting the whole community by the ears.”
—Washington Irving (1783–1859)
“A considerable percentage of the people we meet on the street are people who are empty inside, that is, they are actually already dead. It is fortunate for us that we do not see and do not know it. If we knew what a number of people are actually dead and what a number of these dead people govern our lives, we should go mad with horror.”
—George Gurdjieff (c. 1877–1949)
