Summary

The local heat transfer coefficient for laminar gravity controlled Nusselt type film condensation is calculated analytically. The area average mean value is calculated by numerical integration of the local value over the condensation surface or, alternatively, by integrating the condensate flow rate along the border of the heat transfer area. The results for the elliptical tube of finite and infinite length are compared with those obtained for an equivalent circular tube of equal surface. The elliptical deformation (flattened at the side) increases the heat transfer coefficient, especially with short tubes.
