An experimental study of natural convection heat transfer conducted with water and thirteen aqueous polymer solutions obeying the power‐law model, varying in flow behavior index from 0.3 to 0.99, and consistency index between 10 and 5 × 10 3 , showed that the behavior of these solutions justifies the theoretical treatment of this phenomenon proposed by Acrivos (10) . The heat source was an internally electrically heated copper sphere, 5 inches in diameter, and designed to provide an isothermal surface.
