Experimental Study on the Dynamic Process of a Water Drop with Additives Impact Upon Hot Liquid Fuel Surfaces

Перенос Вещества Составной Капли В Интрузивном И Импактном Режимах

“…Исследование переноса вещества импакта капли в глубокой жидкости продолжается более полутора сотен лет, начиная с работ [1,2] где был рассмотрен процесс формирования многоярусной системы вихревых колец, и остается актуальным ввиду теоретической обоснованности и ряда прикладных задач: методы обеспечения противопожарной безопасности [3], химической, нефтехимической и биологической промышленности. Повышение пространственного и временного разрешения экспериментальной техники, применение коротких импульсов видимого и рентгеновского диапазона, применение химически активных веществ позволяют проследить наиболее тонкие и быстрые компоненты картин течения импакта капли [4].…”

Dynamic Process of Single Water Droplet Impinging Burning Liquid Pool Existing on a Water Layer

“…9−13 For some examples, Manzello et al 9 experimentally studied a water and HFE-7100 droplet impinging onto a hot peanut oil surface and found the phenomenon of water explosion. Lan et al 10 carried out experiments on a single droplet impacting on a heated alcohol and molten ghee surface and found that vapor explosion only could be observed for a purified water droplet impinging onto a 493 K molten ghee surface. Wang et al 11 also performed a series of experiments to explore the dynamic process of a single water droplet with or without additives impinging onto the heated molten-ghee surface and pointed out that the vapor explosion occurred only for pure water droplet.…”
