Numerıcal Estımatıon Of The Condensate Flow Rate On The Condenser Pıpe

In this paper, using Fluent computational fluid dynamics program, the condensing water flow rate was numerically estimated calculating the outer surface- heat transfer coefficient of the condenser pipe. An user defined function wroten with C++ code was interpreted to Fluent program. The fluid is water, the flow is single phase, steady state and turbulent. The outer environment is saturated vapour. This method; especially, in the experimental studies thought the condensing condition, the fact that the heat transfer coefficient on the pipe’s outer surface and condensate flow rate are predicted numerically and some probable ideas about the experiment can be discussed previously is able to be obtained.
