The paper presents a state of the art review of fundamental research of heat transfer process in liquid sprinkled heat exchangers placed in atmospheric and also in vacuum chamber. It compares the structure of atmospheric and vacuum stand. In this article, the temperature falls are experimentally investigated in the condensation and boiling regimes on the experimental tube bundles. The results were obtained by analysis of thermograms of the tube bundles during operation period.
The operating mode of a gas turbine depends not only upon the intake air parameters but also upon a degree of regeneration. The paper analyses the effect of a regeneration degree on the operation of a considered GT 750-6 gas turbine using a special software developed for this purpose. Based on case calculations, the effect of a degree of regeneration on the specific power and thernal efficiency of the actual GT 750-6 gas turbine is quantified. and Obsahuje seznam literatury
