Laminar film condensation on the outside of a horizontal cylinder with forced vapor flow and noncondensables present

Includes bibliographical references (pages 28-30)A simplified computer solution for laminar film condensation with forced flow and noncondensables (air-steam) present was modified to include variable wall temperature and extend the solution beyond the boundary layer separation point to the bottom of a horizontal cylinder. Local condensation heat transfer rates for isothermal and variable wall temperature distribution based on experimental results up to an angle of 90?? on the cylinder were compared to an experimental work and to a numerical boundary layer solution for the stagnation point.\ud 1. It was determined that increasing the velocity increases the heat and mass transfer rates substantially.\ud 2. Decreasing the mass fraction of air increased the heat and mass transfer rates.\ud 3. Decreasing the bulk to wall temperature increased the heat and mass transfer.\ud 4. The percent difference between experiment and theory for the heat transfer at the stagnation point were in agreement within 7% for all cases tested.\ud 5. The percent difference between experiment and theory for the heat transfer at angles of 45?? and 90?? were within 3% and 20% respectively for velocities greater than 5 ft/sec, but were as high as 97% and 139% for the low velocities (.96 ft/sec).\ud 6. The variable wall temperature distribution did not increase the accuracy of the results.\ud 7. No error estimations were performed on the overall heat and mass flux rates due to insufficient experimental data for the range of parameters tested
