Summary

STEADY-STATE NATURAL CONVECTION IN A TOROIDALLOOP WITH A HEATED DIAMETRICAL BRANCH AND COOLED SIDE BRANCHES IS STUDIED. THE LOOP IS ROTATED TO VARY THE TILT ANGLE OF THE DIAMETRAL BRANCH. A ONE-DIMENSIONAL ANALYSIS PROVIDES THE FLUID VELOCITIES AND TEMPERATURE DISTRIBUTIONS IN THE LOOP. WITH INCREASING TILT FROM THE VERTICAL, THE FLUID IN THE LOWER SIDE BRANCH SLOWS DOWN AND REVERSES. THE FLOW THROUGH THE CENTRAL BRANCH INCREASES AND THE MAIN RETURN PATH IS THROUGH THE UPPER SIDE BRANCH. COMPARISON EXPERIMENTS ON AWATER-FILLED GLASS LOOP ARE IN QUALITATIVE AGREEMENT WITH THE ANALYSIS AND MULTIPLE STEADY STATES ARE OBSERVED.
