A theoretical study has been performed to optimize the fin shape and fin dimensions of a horizontal low-finned tube used in shell and tube condensers with shell-side condensation. A new class of high-performance fin and a rectangular fin are examined for theoretical consideration. Extensive numerical calculations with systematically changed values of fin dimensions and bundle depth are performed to optimize the fin geometry with HCFC-123 as a condensing fluid. Under typical operating conditions, the mean overall heat transfer coefficient of a tube bundle with a vertical bundle depth of 30 is improved by 460 and 420 percent over the smooth tube value, using the low-finned tubes with the new class of high-performance fin and the rectangular fin, respectively.
