| Abstract: | The paper investigates the factor of winglet height on heat transfer enhancement performance of test core of finned oblate oval tube heat exchangers with six wing-type vortex generators per tube via mass/heat transfer analogy of naphthalene sublimation. As a referencable theoretical foundation in following design work, the present study evaluates the effect of change of winglet height on heat transfer and pressure drop characteristics of such type heat exchangers. |
