    Abstract

    Numerical results have been presented in the literature for surfaces with tubes arranged in a regular 60 degree layout and approximating equations have been proposed for layouts other than 60 degree. The first part of this paper presents numerical results for non-60 degree configurations which demonstrate that the approximating equations are perfectly adequate for engineering applications in these cases. The second part of the paper presents numerical results for surfaces in which louvres have been cut for heat transfer enhancement. The results demonstrate that cutting of the fin material to form the louvres results in a significant reduction in fin efficiency, which must be taken into account in assessing the enhancement effect of the louvres.
