The comparative assessment of the thermal efficiency of the in-line beams of the flat-oval tubes with partial ribbing developed in the NTUU “KPI” and of the round tubes with cross-welded and rolled-on spiral-strip finning were analyzed. The advantages of the heat transfer surfaces of the flat-oval tubes with partial ribbing were shown.References
