Corresponding states correlation for maximum heat flux two-phase closed thermosiphons.
Author(s) : GOLOBIC I., GASPERSIC B.
Type of article: Article, IJR article
Summary
A method is presented for the prediction of performance limit in two-phase closed thermosiphons based on the thermodynamical corresponding states principle. Molecular weight, critical temperature, critical pressure and acentric factors are needed instead of thermodynamic and transport properties of fluid at a given temperature. Developed corresponding states correlation for maximum heat flux is found to be in fairly good agreement with the 436 experimental data for 12 nonpolar and polar fluids with fill ratio greater than 0.4 in vertical two-phase closed thermosiphons with an inner diameter of 3-34 mm and the ratio of the evaporator length to its diameter with values of up to 325.
