Abstract

Dropwise condensation and filmwise condensation are experimentally investigated with the help of an experimental setup, by varying the mass flow rate of the cooling water. Dropwise condensation is achieved in a nickel-chromium coated copper tube, whereas filmwise condensation is seen in non-coated plain copper tube. The heat transfer co- efficient for both the cases are calculated experimentally and theoretically by using the Nusselt's formula of condensation. From the evidence, the most effective method of condensation by varying the mass flow rate can be found. This is necessary to understand the theory of dropwise and filmwise condensation. The paper contains the experimental steps involved in performing the experiment, precautions, and final result of the experiment. An error analysis is to be made to check the accuracy of experimental and theoretical results.

Keywords
