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)
“Not too many years ago, a child’s experience was limited by how far he or she could ride a bicycle or by the physical boundaries that parents set. Today ... the real boundaries of a child’s life are set more by the number of available cable channels and videotapes, by the simulated reality of videogames, by the number of megabytes of memory in the home computer. Now kids can go anywhere, as long as they stay inside the electronic bubble.”
—Richard Louv (20th century)
