This thesis describes a unique and useful semi-experimental approach for innovating fin-tubes – towards addressing critical issues of a popular heat exchanger that is extensively used in the modern power generation sector. The approach consists of a unique synthesis of experiments, modeling and reliable computations. These heat-exchangers involve transfer of heat from warm-to-hot air that flows across a tube-bundle into the flowing fluid within the finned tubes. For a specific pair of traditional and innovative fin-tube designs used in a standard staggered tube-bundle arrangement, the approach yields comparative values of air-side thermal and pressure-drop resistances on a per tube basis. Up to 40 - 60% improvement in per-tube energy efficiency parameter (ratio of rate of heat removal to consumed pumping power associated with pressure-drop) is demonstrated for the innovative fin-tube over the traditional one for commonly encountered conditions in the heat-exchangers of interest.
