Axially Homogeneous Convective Turbulence in a Long Vertical Tube

Jaywant H. Arakeri, professor in the Department of Mechanical Engineering in the Institute of Science in Bangalore, India, will discuss a relatively new and unexplored type of turbulent flow created by an unstable density difference created across the ends of long vertical tube.

This flow may be considered to be a free convection analog of pressure driven pipe flow. Both are axially homogeneous, one is driven by a linear density gradient and the other by a linear pressure gradient. This flow has many interesting features: the mean velocities, and the mean Reynolds shear stresses are zero; thus the turbulent production due to shear is zero and is solely due to buoyancy. Near the tube walls, we have shear free turbulence, which does not decay with time.
