Correlations for Mixed Convection Flows Across Horizontal Cylinders and Spheres
An attempt is made to summarize the analytical and experimental results of several representative studies for these two flow configurations in simple correlation equations that can be employed in heat transfer calculations. The present correlation equations are for air flow and in some regions are more accurate in predicting measured results (an improvement of more than 10 percent) than those presented by S. W. Churchill.
