Three‐dimensional natural convection patterns in an enclosure under conditions simulating flow in glass‐making furnaces have been calculated using an approximate method in which solutions for the temperature and velocity fields in orthogonal two‐dimensional planes are superposed. The computational method was tested by comparison with measurements of the temperatures and velocities in an enclosure heated and cooled from above and with a controlled heat loss from the sides. Good agreement was found between measurements and computations under conditions of interest in glass‐making furnaces, wherein the motion in one of the two orthogonal planes is dominant.
