Convection in a long vertical tube due to unstable stratification – A new type of turbulent flow?


We present experimental results of free convection in a vertical tube due to an unstable density difference imposed between the two (open) ends of the tube. Two tanks of fluids connect the two ends of the tube with the top-tank fluid heavier than the bottom-tank fluid. We use salt mixed with water to create the density difference. The convection in the tube… (More)
