An apparatus to measure dropwise condensation heat transfer coefficients of steam
apparatustomeasu00shar.pdf (5.788Mb)Abstract
An experimental apparatus was designed and constructed
for the purpose of determining dropwise condensation heat
transfer coefficients on condensing surfaces of different
thickness. The equipment included a completely self contained
condensing chamber which enclosed both the boiler
and condensing surface. Variable temperature cooling water was utilized to control the heat flux.
A thin film resistance thermometer was constructed to
obtain the average surface temperature of the condensing
surface. Inability to obtain linear and repeatable calibration
data with this thermometer resulted in its being
discarded. An intrinsic thermocouple was used in lieu of
of the thin film resistance thermometer.
