Download Boiling Heat Transfer and Positioning of the Evaporator Pipe

The paper deals with special questions regarding the arrangement of evaporation systems of gravity circulation boilers. General terms like (e.g.) the critical heat flux are described with the focus to optimize the evaporation process in the case of inclined and horizontal arranged evaporator pipes.

The focus was to optimize the cooling- process of these pipes and the avoiding of dynamic instabilities, especially the generation of density wave oscillations (DWO). The text depicts ways to avoid and calculate the appearance density wave oscillations and predicts possibilities to optimize the flow conditions and therefore the cooling conditions in the case of inclined and horizontal arranged evaporator pipes. The result of the text should be to enable the designer to design, optimize and judge inclined and horizontal arranged evaporator pipes properly.
