Fin Shape

To realize the maximum convective transfer of heat or mass, the fins in a plate-fin type heat exchanger must be exactly spaced for an unsupported length at least eight times the fin spacing. Manufacturing tolerances cause imperfect fin spacing and fin shape. These imperfections have been statistically modeled as either nonuniform fin spacing or “bulginess.” By statistically combining nonuniform fin spacing and bulginess into a unique “total channel deviation” parameter, convective transfer penalties and flow pressure drop gains can be predicted. Predictions are supported by experimental measurements.

Augmented Lagrange Multiplier

A computer code has been developed for analysis of air-cooled heat exchangers and was coupled with a numerical optimization program to produce an automated air-cooled, heat-exchanger design and optimization procedure. A general iteration free approximation method was used for the analysis which calculates the mean overall heat-transfer coefficient and the overall pressure drop for many flow arrangements. The analysis takes into account the variation of the heat-transfer coefficients and the pressure drop with temperature and/or length of flow path. The code is not limited to surfaces found in the literature, but will accommodate any triangular pitch bank of finned tubes in multiple-pass configurations. The numerical optimization code is a general purpose program based on the Method of Feasible Directions and the Augmented Lagrange Multiplier Method. The capability is demonstrated by the design of an air-to-water finned-tube heat exchanger and is shown to be a useful tool for heat exchanger design.
