Longitudinal fin conduction in multipass cross-counterflow finned-tube heat exchangers.

Author(s) : HEUN M. K., CRAWFORD R. R.

Summary

The effects of longitudinal fin conduction on multipass cross-counterflow heat exchanger performance are considered in the study. The nondimensional differential equation system that describes the temperature distributions in the fluids and fins is solved in terms of normalized heat exchanger thermal resistances. Model results are presented in a series of graphs that show the regimes in which longitudinal fin conduction must be considered. The locus of points that describes optimal heat exchanger performance is presented with a simple correlation. The application of the results to heat exchanger design optimization is discussed.
