    摘要: Группа изобретений относится к гидродинамическим системам и может быть использована в областях промышленности, применяющих пульсирующий режим течения жидкости. В способе генерирования колебаний жидкостного потока жидкость из напорной магистрали (11) предварительно разделяют на два потока снаружи вихревой камеры (1), внутри нее их закручивают с помощью каналов с разными скоростями в противоположных направлениях и при этом разделяют с помощью перегородки (4) со сквозным каналом (5). Поток с большей скоростью закручивают с помощью каналов закрутки (2). Поток с меньшей скоростью закручивают с помощью каналов закрутки противоположной ориентации (3) и связывают через канал (9) с полостью с регулируемой упругостью (8), закрытой герметичной эластичной оболочкой (10) и установленной в трубе (7) вдоль ее длины. В результате упругого взаимодействия жидкость в канале (9) получает импульс, направленный в вихревую камеру (1), с помощью которого происходит резкое торможение закрученных потоков и импульсное увеличения расхода через выходное сопло (6). Изобретение направлено на повышение эффективности преобразования постоянного потока жидкости в пульсирующий поток за счет снижения гидравлических потерь и потребляемой гидравлической энергии.

    摘要: The invention relates to methods for producing acoustic and ultrasonic resonance oscillations in liquid and gas flows and can be used in various industries for carrying out highly efficient and deep emulsion, regeneration, polymerisation, dispersion and homogenisation processes and for mass and heat-exchange processes. The aim of said invention is to obtain a wide range of phase-frequency characteristics during a highly intensive liquid or gas processing by means of resonance oscillations occurring when an inlet stream passes a closed space in an opposite direction with respect to an outlet stream at an angle ranging from 1 DEG to 45 DEG , thereby producing an additional pulsation of treated liquid or gas streams due to the fact that said inlet and outlet streams move in a closed space according to a sinusoidal or sawtooth trajectory.

    摘要: The invention concerns a method for producing selectively controlled pressure pulses in a mass of gas (1), in particular contained in a space (27) of large dimensions. In order to achieve a sufficiently high power in the pulses these are generated by a valveless displacement machine (2), in which the pressure when the machine (2) opens towards its outlet port, differs from the pressure of the mass of gas. The pulse is generated as the working fluid, due to said pressure difference, at high velocity flows through the outlet port (23). An acoustic power of the generated pulses of up to 20 kW can be attained by the method. The invention also concerns a device for performing the method.
