Heat and Flow Study of the Internally Finned Tubes with Different Fin Geometries

Heat and flow enhancement is a critical weapon for the design of highly efficient, compact, cost-effective devices. The objective this analysis detailed examination implementation different fin shapes on internal side tube aiming heat enhancement. reference empty examined, while use circular, rectangular, triangular fins also studied. Different simulations were conducted with developed computational fluid dynamic model, results expressed in terms. model was validated by comparing theoretical expressions Nusselt number, as well friction factor. obtained evaluated calculating convection coefficient, pressure drop, factor, pump work, mean wall temperature, Bejan number. According to calculations, rectangular best solution; second choice, less efficient improvement method circular fins. Regarding transfer enhancement, lead 36% 25%, 23% compared tube.
