Natural-convection heat transfer from uniformly heated horizontal cylinders to air was investigated experimentally for a bank of cylinders in staggered arrangement. The heat transfer coefficients for seven cylinders, arranged in a vertical array, were measured for varying cylinder spacings in the horizontal and vertical directions. A correlation equation for evaluating average heat transfer coefficients was deduced for banks of cylinders. It was shown that this equation was also applicable to cylinder banks in an in-line arrangement.
