Description

technical field [0001] The invention relates to a numerical simulation method for cavitation of RP-3 aviation kerosene, and relates to a method for reducing cavitation problems caused by RP-3 aviation kerosene in the industrial field, belonging to fluid mechanical engineering, multiphase flow and calculation field of fluid mechanics. Background technique [0002] When the internal partial pressure of the liquid at a certain temperature is reduced to the saturated vapor pressure of the liquid, vaporization will occur, and the gas dissolved in the liquid will also precipitate out to form bubbles (also known as voids, cavities). After the flow moves to a place of higher pressure, the vapor in the bubble recondenses and the bubble collapses. The process of the generation, development, and collapse of cavitation in this liquid flow, as well as the resulting series of physical and chemical changes, are called cavitation. The occurrence of cavitation often leads to a decrease in ...
