Local heat transfer coefficient and pressure drop of two phase steam in a vertical tube.
Abstract
In the early days of steam generation for power, saturated steam
was used a great deal, but in order to achieve higher thermal efficiencies
and reduce errosion of steam turbine blading the steam power industry
rapidly extended steam conditions into the superheat region. Except for
a small amount of data recorded for boiling in vertical tubes with free
convection no extensive study had been made of the heat transfer and
pressure drop characteristics of wet steam.
