Turbulence at very high Reynolds numbers


Professor Alexander Smits

Department of Mechanical & Aerospace Engineering, Princeton University


Abstract

The performance of vehicles such as submarines, ships, airplanes and missiles depends strongly on the effects of Reynolds number on the fluid mechanics of the external and internal flows. Large vehicles always means large Reynolds number, but they are typically designed at Reynolds numbers much lower than the full-scale. Extrapolation to full-scale conditions is not wholly reliable, and this sometimes leads to unwelcome surprises, which may necessitate an expensive re-design. We have very little information on the behavior of turbulent flows at high Reynolds number and in this seminar, the effects of Reynolds number on turbulent flows is illustrated using recent research results obtained at Princeton, and the implications for design procedures is discussed.
