Turbulent cross-flow in a staggered array of finned tubes

This paper describes an experimental study of highly turbulent cross-flow through a staggered array of finned tubes in sub-critical flow. Measurements of the mean and root-mean-square fluctuating components of tangential velocity within the inter-fin region were obtained about a cylinder in fully developed conditions. Measurements are compared with the results of an earlier study within a bank of plain tubes.
