Impacts of hydrocarbons impurities on heat transfer deterioration

Hydrocarbon impurities in Liquified Natural Gas can lead to unwanted occurrences like heat transfer deterioration and pseudo-boiling phenomena. It can pose a challenge for cooling channels in rocket engines. This study examines the impacts of hydrocarbon impurities on heat transfer deterioration in cooling channels. The Reynolds averaged Navier Stokes equation is solved numerically for different commercial LNG flows in circular pipes under supercritical conditions. The thermophysical and transport properties are calculated using the 2008-GERG equation of states and extended corresponding states models.
