Summary

EXPERIMENTS HAVE BEEN PERFORMED WITH TURBULENT AIR FLOW IN A TUBE WITH UNIFORM AND WITH TOP-HALF HEATING ; THE FLOW WAS HYDRODYNAMICALLY FULLY DEVELOPED AT THE START OF THE HEATED SECTION, AND THERE WERE NEGLIGIBLE BUOYANCY EFFECTS. NUMERICAL SOLUTIONS OF THE MEAN MOMENTUM AND ENERGY EQUATIONS WHICH USE THE SUGGESTION THAT THE RATIO OF RADIAL-TO-CIRCUMFERENTIAL TURBULENT DIFFUSIVITIES IS EQUAL TO THE CORRESPONDING RATIO OF MEAN SQUARE VELOCITY FLUCTUATIONS IN THESE DIRECTIONS AGREE WELL WITH THE EXPERIMENTAL RESULTS.
