Individual row heat-transfer coefficients are presented for air flowing across 10-row in-line tube banks at close back spacings with heat flow from air to tube. The Reynolds number range covered is approximately 1000 to 20,000 with heat fluxes of 640 Btu/hr-sq ft to 12,500 Btu/hr-sq ft. The effect of both tube row number and Reynolds number is shown. These effects are different for tangent (tubes touching in direction of airflow) and nontangent tubes.
