Исследование падения капель Ñ€Ð°Ð·Ð½Ñ‹Ñ Ñ€Ð°Ð·Ð¼ÐµÑ€Ð¾Ð² на твердую Ð¿Ð¾Ð²ÐµÑ€Ñ Ð½Ð¾ÑÑ‚ÑŒ

Abstract

Предметом настоящего эксперимента является прямое воздействие искусственно увеличенной капли жидкости на ÑÑƒÑ ÑƒÑŽ, твердую, гидрофобную Ð¿Ð¾Ð²ÐµÑ€Ñ Ð½Ð¾ÑÑ‚ÑŒ (гидрофобные свойства Ð¿Ð¾Ð²ÐµÑ€Ñ Ð½Ð¾ÑÑ‚Ð¸ определяются возможностями материалов эксперимента). Рассматривается случай относительно высокой скорости удара, не превышающей порог разрыва капли (число Вебера We≫1, число Рейнольдса Re≫1), когда капля деформируется ударом превращаясь в тонкий диск, ограниченный ободом. Цель работы – исследование поведения Ð¸ÑÐºÑƒÑÑÑ‚Ð²ÐµÐ½Ð½Ñ‹Ñ ÐºÐ°Ð¿ÐµÐ»ÑŒ Ð±Ð¾Ð»ÑŒÑˆÐ¸Ñ Ñ€Ð°Ð·Ð¼ÐµÑ€Ð¾Ð² и сравнение с существующей теоретической моделью, чтобы расширить возможности ее применения.

Keywords
