Abstract

An experimental study has been made of the mechanism of thermogravitation effect on turbulent flow in a circular horizontal tube. Two stable structures of secondary flow have been registered, and the boundary of transition of one structure into another has been determined. Bueyancy effect on turbulence has been revealed.
