The effect of vapour shear on retention angle had been reported by Namasivayam and Briggs (2005 2006) and Fitzgerald (2012).
Assuming equilibrium conditions this would result in about 10% ethanol in the vapour but again assuming equilibrium this would again be 1% in the condensate which would have a negligible effect on the surface tension.
1) at the same vapour-to-surface temperature difference and vapour velocity.
This was independent of vapour-side temperature difference but a fairly strong function of vapour velocity.
It was interesting to note that assuming equilibrium conditions in the test section the ethanol concentration in the vapour was at least more than 10 times than in the liquid (Table 1).
Conclusion: Experimental data of heat transfer and condensate retention have been obtained for condensation of steam-ethanol mixtures over a range of vapour velocities on a finned tube.
