H911 Film and Dropwise Condensation Unit
Although the differences in the modes of boiling heat transfer are generally recognised many students are not aware that two distinct modes of condensation can occur. The H911 is a self-contained bench top unit that allows the investigation of heat fluxes and heat transfer coefficients during the condensation of steam.
The considerable difference between the appearance and heat transfer rates of dropwise and filmwise condensation are clearly demonstrated. Heat fluxes approaching 1000 kW/m2 can be obtained.
