“…These results confirm the trend of decreasing the HTC with increasing the concentration of NGC [9,10,27] and expand the range of the investigation by higher concentrations of NCG. For air-steam condensation in a vertical tube, a decrease in the HTC below the value of 200 W/m 2 K was observed in a concentration of more than 50 % of NCG.…”

“…For the condensation of steam with non-condensable gases outside a horizontal tube, a decrease in the condensation heat transfer coefficient (HTC) begins even in low concentrations of NCG and the decrease significantly rises with concentrations of NCG [7]. For air-steam condensation on a vertical tube, a decrease in the HTC below the value of 1000 W/m 2 K was observed in a concentration of more than 10 % of a NCG [8,9]. For the condensation of water vapour in a mixture with a NCG, which may also contain small mechanical impurities, it is suitable to use condensers in a vertical tube-side configuration [4].…”

“…Для інтенсифікації тепломасообмінних процесів у плівкових апаратах з вертикальною теплообмінною поверхнею використовують різноманітне оребрення [1][2][3][4][5][6][7][8][9][10]. Враховуючи тісний зв'язок питань гідродинаміки плівки рідини та інтенсивності теплообміну, доцільно проаналізувати основні параметри плівки та мінімальної щільності зрошення рідиною поверхні з повздовжнім оребренням.…”

“…Tarasov carried out experimental studies of heat transfer during steam condensation on a bundle of slightly inclined tubes with and without non-condensable gases at different steam pressures [8]. Fan in his work conducted experimental study of pure steam and air-steam mixture condensation on vertical corrugated and smooth tubes, respectively [9]. Those studies were carried out under different pressures and air content of the air-steam mixture.…”
