Heat transfer in parallel-flow staggered banks of tubes with various relative spacings

Heat-transfer data for parallel-flow staggered banks of tubes with s/d ratios of 1.16, 1.2, 1.34, 1.4, and 1.5 are examined. The experiments were performed with water at Reynolds numbers ranging from 2·10³ to 7.10⁴.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 16, No. 1, pp. 47–53, January, 1969.
