An analysis of the thermal and physical properties of organic vapours and steam condensing on teflon coated mild steel (m.s.) substrate in different patterns has been carried out. Photographs of the pattern of vapours (other than filmwise) have been presented. The properties of thirty three vapours experimented for their pattern of condensation are tabulated. Eventhough for steam, the coefficients are higher than for organic vapours, for both filmwise and dropwise condensation (dc.) due to its advantageous physical properties and the extent of augmentation in d.c. is also higher, it was observed from the experiments that there is advantageous enhancement for organic vapours also inspite of their physical properties being at disadvantageous levels and their characteristic changes with other parameters like temperature. These characteristics wherever possible are discussed.
