• Experiments have been carried out on free convection heat transfer from horizontal cylinders in staggered arrangement. Average heat transfer coefficients of individual cylinders and the whole cylinder array were measured in order to clarify dependence of those coefficients upon the geometric figures including spacing and off-set distance between two cylinder lines. Visualization of flow fields around the array has also been tried to explain the heat transfer behavior of cylinders in array. The experiments show that there exist some optimum values of cylinder spacings and the off-set distances to increase the heat transfer coefficients and that the heat transfer promoting effect can be expected especially when the array is set between parallel walls.
