Abstract

Изобретение относится к гидродинамике и предназначено для снижения гидравлических потерь в напорных трубопроводах гидроэнергетических станций и в трубопроводах для транспортировки различных жидкостей и газа, а также в горнорудной промышленности для транспортировки руды в виде пульпы. Сущность изобретения заключается в следующем: способ снижения гидравлических потерь в трубопроводах, содержащий импульсные вибрации, основан на том, что импульсные вибрации создаются периодически по длине трубопровода и концентрически по его диаметру к центру потока и/или дополнен операциями создания винтовых потоков жидкости в области её контакта со стенками трубопровода и/или обеспечения бегущих стоячих волн вдоль направления потока, при этом создаются по крайней мере три винтовых потока жидкости в виде вихревых шнуров, бегущая стоячая волна обеспечивается за счет создания встречных импульсов вибраций с разной частотой, а параметры концентрических вибраций выбирают в зависимости от свойств жидкости и диаметра трубопровода.The invention relates to hydrodynamics and is intended to reduce hydraulic losses in pressure pipelines of hydropower stations and pipelines for transporting various liquids and gas, as well as in the mining industry for transporting ore in the form of pulp. The invention consists in the following: a method of reducing hydraulic losses in pipelines containing impulse vibrations, based on the fact that impulse vibrations are created periodically along the length of the pipeline and concentrically along its diameter to the center of the flow and / or supplemented by operations of creating helical fluid flows in the area of its contact with the walls of the pipeline and / or providing traveling standing waves along the direction of flow, while creating at least three spiral fluid flows in the form of vortex cords, running one hundred The wave wave is provided due to the creation of oncoming vibration pulses with different frequencies, and the parameters of concentric vibrations are chosen depending on the properties of the liquid and the diameter of the pipeline.
