Résumé

The axial dispersion model for cross-flow heat exchangers is investigated to predict steady state thermal performance more accurately. This model takes flow maldistribution and backmixing into account and is simple and effective in describing their effect on the temperature effectiveness of a heat exchanger. An exact solution together with its asymptotic form for high dispersive Péclet numbers is obtained. Charts are presented, which are useful for the design of compact cross-flow heat exchangers.
