Summary

THE MEDIUM SURFACE MAY BE INCLINED WITH RESPECT TO THE GRAVITY VECTOR. BOTH THE CYLINDER AND THE MEDIUM SURFACES ARE MAINTAINED AT CONSTANT UNIFORM TEMPERATURES. TWO CASES ARE CONSIDERED. IN THE FIRST CASE, THE SURFACE OF THE MEDIUM IS IMPERMEABLE TO FLUID MOTION WHILE IN THE OTHER PERCOLATION THROUGH THIS SURFACE IS ALLOWED. THE COMPLICATED GEOMETRY IS HANDLED THROUGH THE USE OF BICYLINDRICAL COORDINATES. THE RESULTS INCLUDE A DESCRIPTION OF THE FLOW AND THE TEMPERATURE FIELDS AS WELL AS A CORRELATION FOR THE NUSSELT NUMBER. IN ADDITION, IT IS DEMONSTRATED THAT AN OPTIMAL BURIAL DEPTH EXISTS FOR WHICH HEAT LOSSES FROM THE PIPE ARE MINIMIZED. THE ANALYTICAL RESULTS ARE COMPARED WITH NUMERICAL CALCULATIONS.
