Heat transfer correlation has been developed, assuming a simple cubic model of open cell foam. The cross-linked porous structure is equivalent to a bundle of independent, slender tubes with protrusions. It may be presumed that the projected struts either cause an increase in heat transfer coefficient or they act as extended surfaces or fins. The effect of these protruded filaments has been judiciously integrated within the empirical correlation for cross-convective flow over the bank of smooth tubes. An augmentation in foam heat transfer coefficient has occurred due to cross-connections in struts. An excellent agreement has been observed between the predicted correlations and the existing ones which have been established through experimental data. (C) 2008 Elsevier Ltd. All rights reserved.
