| Summary: | Hydrodynamic instabilities are regarded as important but are undesirable occurrences for the systems
used in process industries, which involve steam. These instabilities affect to a great extent the life line
of the safe operation of their systems by inducing thermal stresses and steam induced water hammers.
On the basis of system operational analysis, it was found that condensation induced hydrodynamic instabilities
were responsible for one third of the destructive events in steam driven systems and their attributes
in power and process industry. Thus it becomes vital to investigate the influence of critical
parameter such as sub-cooling to curb the destructive effects due to hydrodynamic instabilities on to
the process equipment. Here for steam water two phase flows, the attenuation of hydrodynamic instabilities
due to sub-cooling and inlet pressure has been investigated. It was found that sub-cooling has more
pronounced and notable effect on the attenuation of these instabilities |
