Heat transfer coefficients for a horizontal multi-tube rotating condenser have been experimentally determined. The effect of the rotational speed of the condenser tube bundle and the flowrate of the cooling water on the overall heat transfer coefficient was studied. A maximum enhancement in the ...

The parameters which cause the dynamic variation in the condenser performance are the finite thermal capacity of the radiative condenser panel, effective sky-temperature, ambient temperature, humidity ratio and the condensers overall heat transfer coefficient. The presented model is solved numerically and ...
The invention discloses a determination method of a total heat transfer coefficient of a condenser of a thermal generator set. The method is as follows: generator set load, circulating water flow, circulating water inlet temperature, the practical total heat transfer coefficient of the condenser, th...

In our present work, the author has considered a conventional design procedure and empirical correlations of surface condenser for the analysis of critical parameters like pressure drop, dirt factor, overall heat transfer coefficient, velocity of circulating water, rate of condensation, outlet ...
The overall heat transfer coefficient of stainless steel tubes is not necessarily worse than that of copper tubes, and stainless steel tubes are more superior after a period of operation. The reason is that the contaminated and fouled cooling pipe will have an adverse effect on heat transfer. Th...
