In the race to curb energy and oil consumption, zeroing of wall frictional forces is highly desirable. The turbulent skin friction drag at the solid/liquid interface is responsible for substantial energy losses when conveying liquids through hydraulic networks, contributing ap ...

We revisit the classical entrainment experiments for gravity currents on inclined slopes (Ellison and Turner, J. Fluid Mech. 6, 423-448, 1959). We derive an entrainment relation that couples the entrainment rate E to the production of turbulence kinetic energy, the net effect of ...
