Summary

THIS DETERMINATION IS MADE FOR A TURBULENT FLOW OF VISCOUS, INCOMPRESSIBLE FLUID. A FOUR-LAYER MODEL IS USED FOR THE DESCRIPTION OF THE FLOW AND A RELATIONSHIP IS OBTAINED FOR THE CALCULATION OF THE SPEED PROFILE, THE THERMAL EMISSION COEFFICIENTS ON THE INTERNAL AND EXTERNAL WALLS OF THE CHANNEL, THE TEMPERATURE PROFILE. THE HEAT EMISSION COEFFICIENT IS SHOWN TO BE HIGHER ON THE EXTERNAL WALL AND LOWER ON THE INTERNAL WALL OF THE ANNULAR CHANNEL THAN ON THE WALLS OF A PLANE CHANNEL.
