Abstract
We conducted a theoretical and experimental investigation of the hydrodynamic structure and unsteady free-convection heat transfer in a round horizontal tube under different conditions of the second kind. During the experiment the Grashof number varied from Gr=1.54·105 to Gr=7.9·105. Using the interferometric method we investigated the distribution of the temperature field for different structures of free-convection flow in the tube.
