Relative roughness, friction factor, and this man's namesake number are related on Moody diagrams.
For a linearly reductive group, this man's namesake operator gives a notion of averaging and is studied in invariant theory. Much research has been devoted to developing a relationship between the mean velocity's strain rate to a quantity named after this man that is equal to the density times the time average of the fluctuation components. His time averaged equations are the origin of the most important closure problem in fluid dynamics. This man's namesake stress model is the next order improvement over the eddy (*) viscosity linearization. His namesake stress is derived from decomposing turbulent flow into a background and a fluctuation flow and represents the momentum transferred by turbulent flow. Relative roughness, friction factor, and this man's namesake number are related on Moody diagrams. The ratio of inertial to viscous forces is a dimensionless number that characterizes the onset of turbulence that is named after, for 10 points, what scientist?
